Antenna's

So if I was going to make a big antenna say 15ft tall and use an itrip to run it. Would it be able to support that big of an antenna. If not what would I do so it could. Seems like I might need some sort of amplifier and help on where to get one would be great.

Tetrahedron Antenna

Hello I have a question about an idea I have for an antenna that always points to the sky antenna no matter how it lands; this is for a high altitude balloon. My idea was to make an antenna the shape of a tetrahedron, so that one antenna always points up. Does  having 4 antennas diminish the signal from the transmitter at all? Thank you

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.

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.

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.

USB WiFi Antenna Mod

I am working on adding a helical antenna to a cheap USB WiFi adapter.  My question is where do I connect the antenna to existing circuit.  I've attached a closeup picture with three likely points.  My three main questions are: 1) Where to connect the external antenna 2) Do I disconnect the rest of the onboard antenna (my gut says yes) or just add in the new 3) What impedance will the external antenna need to match?  I assume the components between points C&B; and B&A; are for some kind of impedance matching.

I will rubber-coat all straight tube section then apply appropriate wire on to rubber and re-coat with rubber coating. I was then looking to slide slightly over-sized (I.D.) carbon fiber tubing over that. Ground and antenna wire will run through inside of rack turn down stanchion where bolts to roof. Rubber grommet to further insulate & protect wires. I want super reception AM & FM, little to no visible footprint, 1. What wire or such for antenna is best/appropriate? 2. Proper lay out antenna wire? ie., wrapped around primary insulated tubing or laid out length-wise.

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?

Re: dipole HD antenna?

 I noticed in Home Depot 4' x 8' sheets of metal lathe used for putting stucco on housing exteriors.  It was cellular with each cell being an elongated hexagon approx 5/8 inches in length.  The long sides of each cell had been bent at 20-30 degrees (guess) to provide a cavity based substructure for the stucco.  My thoughts went to the fractal antenna posted by williamruckman  on Jan 3, 2009.  An interior attic roof would provide an invisible and safe location similar to the entry point for a dish cable.  The lathe could be shaped virtually without limitation for tuning.  Thoughts??  VR?

Rotating Antennae Wiring Question? Answered

Ok, something I've been thinking about for awhile.  Say you have an antennae/radar dish/etc that rotates 360°. Naturally, you have wires running up to the antennae connecting it to the rest of your circuit/broadcasting/receiving device. How do you prevent the wires from wrapping around the antennae and causing it to stop or causing the wires to break? I suppose you could reverse the antennae every so often to prevent this, but there must be a better way. Also, I figured you could have some sort of connection that rotated around, but it seemed that a rotating connection could be problematic if debris or something got in the way. It also doesn't seem like a very solid way to connect the two devices together.  Not actually building something here, just a curiosity. Thanks!
