Grounding an Antenna

I'm thinkin of puttin up a high antenna. Due to my location with a mountain between me and broadcast towers, reception can be sketchy.  One concern is that of lightning strikes.  But if the antenna is grounded, wont that also ground out the microvoltage radio signals? How do I get microvolt signal without risk of megavolts burning the house down? I've done a wee little bit of google research, but haven't seen this question addressed.

TV antenna

Is it possible to make a tv antenna from an old router? I have an old router and a tv antenna. I am trying to do this because my stupid cable provider won't pick up a second CBS. Then my TV tower fell about 5 years ago. Last month I found this station. It's 79.2 miles away. My little indoor TV antenna pick it up at NIGHT, on CLEAR skies only. (Not in the day) and I have to hold the antenna. I know routers would be didgital (if that has anything to do with it). My tv does have the digital tuner. On digital I can't pick it up, but i do somewhat on analog.

Antenna issues- loss of signal with a DIY antenna Answered

Recently, I have made an HDTV antenna using a video from youtube (http://www.youtube.com/watch?v=EWQhlmJTMzw) and some inspiration from Instructables that I have read. The issue i'm having is that I am slowly losing my signal. I noticed the rust build-up on the end of the fins of it and I have cleaned them up, but it didn't help. Another issue is that I can't seem to pick up a local channel, yet on clear nights I pick up channels from 100 miles away. ( I live in Winchester, Ky and I pick up Cincinatti channels) Anyone have any ideas? Maybe re-work the metal parts with a different type of metal? Maybe a few ideas on different designs?

RFID antenna question. Answered

How sensitive is RFID functionality to the length of its antenna? Specifically, if I had an RFID like this one, cut the antenna and then resoldered it, would the loss in antenna length (I'm guessing about half an inch) affect the workings of the device?

FM radio antennas

Are there any ideas out there for building an FM antenna booster that can be used with the usual whip antenna that comes built into most radios these days. Most of the radios are made in such a way that it is difficult to get at the internal wiring, so the booster would have to be an external unit.

UHF CB radio antennas or scanner antennas anyone?

For a while now I am back to experimenting with various antenna designs for my UHF radio.Started as something entirely different but who cares LOLAnyways, we usually have either a standard whip antenna or a vertical dipole design for mobile use, like on your car.This is a very good design for both types of antennas, mostly due to the short wavelenght compared to the "old" 2m or 27mHz CB radios.Fun fact for at least AU in this regard is that back in the day everyone jumped onto UHF to get away from the overfilled chatter on 27MHz, now the old 2m band is basically dead except for marine use.One thing I really miss on UHF though is distance!Line of sight communication sounds fine at first but then you really have to realise the limits once out and about.As a result we often have to choose between a high gain antenna or a stubby for going into the mountains or being in a convoy.Only way out seems to be the golden middle by opting for one of the 4.5 - 6-5DBI antennas.Neither solution really satisfies me though :(To get around the limitations and have some fun again when sitting high on a mountain I compared various commercial antennas I had.You know, pick someone with a weak signal coming in and hope he hears you and has some time for a chat.Turned out there is not really that much difference in terms of receiving a signal.Quite huge differences though when it comes to the other side being able to hear you!So I jumped onto a basic SWR meter and actually checked my so called factory tuned antennas - all but one were way off the charts here.At least if you are like me and like optimised instead of compromised antenna systems.A Standing Wave Reflection ratio of 1:2 or even 1:2.5 is seen as very acceptable thing on UHF for some weird reason.Back in my glory days no one I knew would have accepted anything above 1:1.3 for his 27MHz system, be it mobil or a station at home.Sure enough, repeating my long distance tests a few days later with tuned antennas resulted in far better results.An antenna for long distance calls or emergencies?!The easiest way to get more distance on UHF is obviously getting the antenna as high as possible.From a nice mountain top you have it way easier than in any urban areas for example.Explains why so many of the long and sturdy antennas are just simple dipoles on a long pole.If you ever checked the feedback for these double quad TV antennas you realise they are literally in the same frequency range.Similar story for all the Yagi antennas for our TV sets that you find on so many roofs these days.Only problem with them is that they usually don't give a damn about transmitting qualities.And of course that they are usually providing around 300Ohm instead of the 50Ohm our radio expects.A TV needs 75Ohm and a balun is used to provide a isolation as well as a matching for the TV.Needless to say I could not accept this ;)My first design was made from aluminium foil glued onto some printed and stiched pages for a double quad.1MHz bandwidth is quite narrow, so the basic square design with about 13.8cm for the sides of the squares was easy.To my surprise by just adding standard RG58 cable this design was very close to 50Ohm already, I had around 60.A few glue sessions later I was able to match it to 52Ohm - close enough for test.Did not want to risk anything with my expensive Icom so I used my cheap Baofeng handheld for the initial tests.Indoor mind you...To me disappointment I seemed to be unable to pick up anything.So let the sanner run and waited...After being bored enough I decided to pick, starting with the antenna and when I moved it the handheld suddenly had a clear signal.Desperate as I was I grabbed the radio and waited for the chat to continue - nothing again...Then it finally hit me: The double quad is quite directional....Sure enough by just turning it slowly I was able to pick up chatter on various channels.Once brave enough to risk it I even got confirmation that people about 10km away could hear me just fine.Time to scale it up a notch...Next design already had the directional problem included as a design feature.I added a director in the front and a reflector in the back.The endless hours of glueing and cutting were replaced by using 12mm wide copper tape and sturdier cardboard.A test with my car on a little "mountain" and the antenna on 2m pole mounted to roof rack gave me, for the first time ever, conversations with people that were over 30km away.I am currently trying to make the entire thing omnidirectional.The omni quad....If you take two double quad antennas and mount them at a 90° angle you end up with very nice 2-lobe pattern, 4 lobes if you don't use a reflector.Problem here though is that these designs really mess with your antenna matching.Not to mention that using it while driving only works at quite low speeds.One day I will do the final design in stainless steel wire though...Anyways, using the directional properties to get an omnidirection radiation pattern meant using 4 seperate antennas with a reflector for each of them.Still left a few dark spots at short range but otherwise really nice for long distance if you don't want to constantly turn your antenna.Getting 4 antennas down to 50Ohm on the connection to the cable was painful to say the least.The problem of taking care of distances to be in the sweet spot for the 477MHz range also meant the design ended up to be quite bulky.One of my lightbulb moments providing good ideas caused me to use one reflector with a double quad either side.Worked almost fine but again provided totally different values to somehow match if it ever should transmit a signal without damaging the transmitter.Obvious conclusion was to buy a new roll of copper tape and to try to get four single antennas into one "housing" without stacking them.Bad idea here was to cross the antennas :(Better idea was to make 4 pyramids out of carboard and aluminium foil.Sadly this resulted in a failure because the 4 sides of the pyramid reflect the signal not flat bt at their corresponding angles.Had to make it really big and use 90° angles, resulting in the signal being reflected like light in these cat-eye reflectors on your bike.After wasting a few days to create the real thing it turned out to not really work properly for the reception already.Even close range signals came in really distorted.I guess the double reflection meant the phase is shifting and cancelling out what the antenna gets.My last desing idea for testing will be with a different approach.Instead of 1/4 Lambda elements I will use small 1/64 Lambda elements.Only about 2cm long means that matching is pain in the behind but if the purpose is just receiving it should be fine.The reflector will be four flat sides like a box with antennas in front of the sides and the cables joined in the center.If you like to fiddle with antennas and don't mind trying a weird looking base antenna on your roof I might be willing to write up a short Instructable based on my designs - let me know in the comments....By the way: it is quite easy to desing this for the common 2.4GHz Wifi bands ;)

DIY WiFi Helical Antenna impedance Problems

First off, I live in the states, but I absolutely hate the imperial system of measurements. I will try to use the metric system as much as possible.I have been attempting to follow hanzablast's Helical WiFi Antenna, but have run into a few snags. I have most of the parts and have a few problems concerning it.1. Instead of a Type N connector my USB card has a RP-SMA connector. Do I have to do anything special (buy a special panel mount/ reverse the connections along the wire) because it has reverse polarity or does it not matter?Edit: I feel foolish, Doing a quick wiki search on Reverse Polarity SMA I found out what it means. Turns out WiFi companies reverse the gender of the inner pin in their connectors. So either I have to find a RP-SMA panel mount jack, or buy a RP-SMA Male to N Male Adapter and a N Female Panel Mount. The latter of the two seems more efficient.2. I understand that having too small of wire can have a detrimental effect on efficiency, but what about using a much larger wire (instead of AWG 16 gauge wire using AWG 4 gauge wire)?Edit: Answered By NachoMahma3. I am having trouble locating a SMA right angle 4-hole solder point panel jack mount other than in bulk buys. Does anyone know where to purchase one separately? Edit: Answered By NachoMahma, but has become a null point.4. I am having a problem with the impedance matching. I have seen several different ways to connect the antenna (142.68ohm impedance) to the SMA Jack (50ohm impedance). I've seen half and quarter circumference turns, quarter wavelengths turns, and triangular strips of copper. Which is best?Edit: I did the math and read my friend's ARRL handbook. Supposedly, a 1/4 wavelength turn of a metal strip with an impedance of 84.463 ohm is what I need. Using TraceSim I figured that I can use part of the copper plate with a size of 12.79033mm in width, 30.775mm long (1/4 a 2.437GHz wavelength), and 0.406mm (.016") thickness placed 8.03mm (1/4 distance between coils) above the reflector plate will give me the exact impedance I need.

Hooking up an FM antenna?

I recently got a new power amplifier/tuner from my dad's buddy. On the back, where you hook up the antennas, there are 4 terminals: 2 for FM and 2 For AM. One on the AM side is for the antenna, and the other is ground. This make sense to me, because an AM loop antenna has two wires which need to be hooked up. On the FM side though, it also has a terminal for ground... From what I understand, FM antennas are composed of a single "wire", like those coming out of radios or the ones on cars. What's the ground on the FM side for?

How do you determine the length of an antenna and the size of a fractal antenna? Answered

In an instructable, the formula for calculating antenna length was given as "length in meters =300 / frequency in MHz".  The example given was for a Bluetooth antenna with a frequency of 2450MHz.  The antenna length was calculated as 300/2450 = 0.1225m = 12cm.  The author then divided it by 4 to make a "quarter wave" antenna length of 30mm.  Why divide it by 4 and what is the benefit of a "quarter wave" antenna.  What is the effect of the conductor leading to the antenna?  If the 30mm antenna is soldered to a 4mm lead, does that result in a 34mm antenna?  For a fractal antenna, should the 30mm length of wire be folded into a fractal shape or should the total fractal antenna be 30mm in width?  I have read somewhere that one of the benefits of a fractal antenna is that they are able to receive signals of different wave lengths.

RF antenna wiring (Possible error)?

For our truck scale, we have small remotes to automatically record the weights. The remotes just do not have the range that they should be getting (Sometimes we have to actually touch the antennas with the remotes). Before I ask my questions, let me explain how they are wired up. There are 16 remotes going to 16 channels in the controller box, The first set of 8 are on one receiver/antenna and the second set is just a copy of the first set. The antennas are just a small whip type antenna connected to the center conductor of the coax, there are then 4 more of those wires pointing down, these ones are connected to the shielding on the coax. There is a 75ft RG6 coax cable running to each of those antennas, This cable runs into the scale shack and connects to the f-type jacks on the controller box. Inside the box, there is a short piece of shielded wire going from the coax jack into the rf receiver. Here is where it gets weird, The center conductor AND the shield both are attached to a single screw terminal on the rf receiver. If my thinking is correct then this basically turning the coax cable itself into the antenna, Am I correct? Why would it be installed like this, Was it a bad installer? How should this be done for optimum performance? Thanks, Kade

Aux In, Usb, and Sd all work fine, but I can't use the FM radio function, due to my lack of an antenna.. I've heard of bending a coat hanger, and shoving it in, and I don't like that shotty work, and I used to have an extension, or an adapter, (Not sure exactly what it was), but It got mediocre reception, and I gave it to a friend that I hooked up a stereo indoors for.. I can find such an adapter cheap, but I want something that will get AWESOME signal.. I know most components that require lengths of wire drop voltage, or signal over distance, such as power cables, Cat5 cables, so on and so forth.. So what can I use, modify, or make to get the reception I want, on a budget? I don't want a crappy fix.. I just want something affordable, reliable, and something that won't look too horrible. I have the stereo mounted to my desk, so not much will be exposed, depending on the length of said antenna, Thanks in advance!!

What do you think about this dish as a WiFi signal booster? Answered

Hello everybody, I am in the process of setting up wireless internet at home, but am still a complete novice in this field. I have just bought a ZyXEL G-202 USB wireless adapter and I am making an antenna of sorts following some instructables as we speak. On my laptop I usually get 1-2 stripes at most when it comes to signal strength, so I was planning to do some piggybacking with my desktop. :) (hey, internet is not cheap here in the Balkans. :P) Anyway, I live in the capital where we have many Cafes and institutions providing free wireless, so why not make the most of it, it's not illegal here. :) The only problem is, I live in an block of flats; so many surrounding buildings tend to block and corrupt the signal. For instance, in my room (using an Acer laptop with built-in wireless) I get a list of 5-6 free (read: unsecured) APs, but the signal is so weak, it's good for nothing. :( Now, having examined my options, I was planning to make an antenna and put it on the roof of the building. But, when I climbed to the top, I found this old abandoned satellite dish SEE PHOTO (I asked around the building and nobody knows who it belongs to. Additionally, it's very run down as you can see, and the cables are torn out, so I was planning on claiming it. :p). Now, my questions are: 1. Can anyone tell me if it's a good idea to use this dish as an antenna, if I weather proof my USB receiver and mount it on the focal point of the dish? (Line of sight (aerial) distance from it to the nearest free wifi hotspot is approx. 600 meters) 2. Is there a possibility that my USB will get too hot, maybe catch fire, because of the signal boost? (Maybe this is a dumb question, but I really don't know much about these things) 3. Finally, I would also need an advice in regard to the cables needed. I already downloaded the "How to extend your USB using UTP" instructable, but since the cable should be about 60 meters long, is there a way to make it not loose too much signal? Thank you all for reading this, and thank you in advance for your advice. Any type of help is welcomed. :)
