Simple CB base station antenna
I don't have access to copper tubing. Can I use strips of aluminum instead? If not, what material do you suggest?

I used your dimensions and mine worked out perfect. - AllanS58
Hello Arnold.If you happen to have used a Channel Master line amp. There is a switch inside the upper box. I think it is buy default in the dual head position ? If you missed this and did not set it single head input it will not work properly. - imzzaudae

I'm thrilled to confirm how well my project antenna is working! The tower is standing. The head is now 35' off the ground and working very well. As everything is out 60 miles, I installed a Channel Master 15db pre-amp and I have 22 channels clear as a bell. Great project
Update:Poor performance above channel 42 prompted me to re read the instructions. I then re measured my tubes.Each tube was 50" a full 8" longer than the plans called for. Then add 2" for the 90 deg elbow and the spacer on each end. After careful measurements where taken.I removed the 90 deg elbows, spacers and caps from both ends of each tube. Cut the pipes 39" then re attached the 90 deg elbows mounting spacers and end caps. Adjusted the 3/4 PVC arm lengths. Re bent the tubes to fit and re mounted the tubes. Boom! The picture cleaned right up on 29 & 42, 51 is now not only there but flawless! Transmitter towers are close. After that everything is 45 and 60 miles.Hoping to get them.Tower is laid out in the back yard. will be mounting the antenna and standing the tower in the next few days. Will post pictures and results. Ron
I found your plans. Made a few adjustments and had at building one of my own.Center plates are cut 6" square - nylon cutting board. 3/4 PVC armsCenter section Nuts and Bolts are 1-3/4 10s. Blue thread lock.All of the other screws are 1/2" 8s. left over from building a garden shed.Pipe is 1/2 inch outside soft copper coil. 84" cut in 2. Added 45s, a short spacer and caps.Everything 1/2" 8 is drilled and tapped.Copper caps are drilled and tapped # 8 for attaching matching transformerShown here without mounting brackets attached.The Antenna is working well at ground level. Looking forward to standing a tower and mounting it properly! RonScrews 1 - 3/4 10s
Thats a chickenshit reply!
BY far the best antenna I have eber made, Although I built mine smaller about a foot and a half.
I don't know how I could make this any clearer. This includes parts list and directions and photos. The video would only add in picking up and using a drill and screw driver and soldering iron which you can get below.

When the window opens type the following in the search bar ...How to XXXXXThe xxxxx represents what you are searching how to do. Then hit your enter key on your keyboard. The most relevant webpages will be first. I usually find what I want on the first page.If you are still having trouble, Ask one of your neighbors who is familiar with tools.
the center conductor of the so239 is soldered to the antenna wire going up. The outer connector of the so239 is where the ground/reflector wire and just passes through a hole to the inside of the mast and hangs down the inside of the mast.http://www.k4icy.com/dipole_connector_so239.jpg
It just hangs there
By how big, you could mean the length of the antenna or the height above the ground. The diameter of the antenna is fixed. By changing the lingth of the antenna. you will change the frequency. The more you change the diameter the more the signal will be degraded.As for height above the ground, The higher the antenna. the better it will work However there are restrictions on height in some areas. If you live close to the flight path of an airport, call the airport and tell them where you live and they can advise you on height restrictions. You can also call your city and see if there are any other height restrictions for your area. If you belong to a homeowners association, check with them. Some do not permit antennas or towers. At some point you will be required to have a light on top to warn aircraft of it's presence. Pretty much everywhere, you are restricted to 500 feet so it does not interfere with aircraft as they stay above 500 feet except for landing or take off..In most areas you have to have room if it falls, it will stay on your property. In other words, if you have a 200 foot tower it must be at least 200 feet from your property line. A 1 acre piece of property is approximately 200 feet by 200 feet, so you would be limited to 100 feet if it is in the center of the property.
If,there is any way someone could do a build on utube of this. I would love to see it.I have always wated to build a omini directional out of rod or tube-pipe copper.With ground radios.Alomost like the A99 or solarcon A99.But, most of them are 17-18.5 feet long.Have always got great skip w/ them.
26 inch Diameter-- the circumference or length will be C= 3.14 x 26 = 81.64 inch length minimum of cooper tubing. So at least 2-two 42 inch cooper tube, bent in a semi 26 circle. NOT a 26 inch tube.. BUT more than 82 INCH COPPER TUBING !!!
What kind of wattage does this setup support? I have a Connex 4600 Turbo pushing right around 200 watts.
This was made by my husband Marvin Felz but I helped some ;)
?Como hacer esto (instructions)?
You need larger wing span for more channels. My RCA antenna is 150 inches which is huge, so you need a big wheel 12ft or larger wheel
this antenna appears shorted to ground.
I built this and I am impressed. It works great, and is omnidirectional. I had a problem pushing the copper tubing through the holes. I would suggest, at additional expense, to drill holes through pvc couplings and then put the tubing through those holes and bend and glue couplings to "star" pipes. I wish I had thought of that before I made mine. All in all agreat easy project that works great!
Do you have a wiring diagram or something? I can't quite understand howto wire this up.
is there a limit (by law) for how big to make it?
Thanks Rich for your reply on length. What diameter do you recommend for best reception 3/8, 1/2, 1" or # 6 or 8 copper grounding wire.
The electrical wire that is attached to the screw hole of the SO239 then goes down the t connector then what did it attach to? Does it just hang there or is it attached to the ground rod driven into the earth?
Would larger diameter copper tubing and a larger loop going to increase my reception. I have about a 10' section of 1' copper tubing left over from plumbing project.
