I like to know if any one build 12 Food stressed parabolic form ARRL Antenna Hand book 19th edition (Page 19-15). I like to build 9 to 12 feet...
Does anyone have a recommendation for a good 30m dipole antenna, or a multi-band that gets great SWR on 30m? I don't have the time to build one...
Aviation LF/MF beacons provide an opportunity to admire electrically-small antenna design on a macroscopic scale and provide the amateur radio...
Would anyone be interested in seeing my unusual antenna tower installation as I work on it? Now that the project is starting to look less like...
Assume we have an array, like a 4-square, another phased array or an electrically steerable parasitic array. Would it be possible/practical to...

Greetings, I am needing help with identifying the mast manufacture in attachment. Require line of sight to obtain internet access and purchased a...
Hey everyone! I’m deciding what antenna I’ll be putting up, and I’d love some suggestions. Sadly, no tower and contest beams here, just a good...
Hi.. I'm considering an 8metre roach pole as part of a Efhw antenna. The vertical element will be the 8m but then it needs to support a 12m...
From the current makers of the Isopole... As it is well-known, the fiberglass antennas are too prone to receiving lightening discharges. The...
Question 1: say you have an area for antennas that is a square with dimensions L by L feet and the frequency is f. You are allowed to have as...
Here is a little comparison between my homemade Terminated End Fed antenna and a traditional EFHW antenna. The difference in receive signal is...
Live in CA and limited antenna options because of HOA. Thinking about a L shaped loop antenna all around the roof line (~ 250 feet circumference,...
Naively, it seems like using an autocoupler at the base of a reasonably long vertical radiator (call it 43 feet - roughly 5/8 wave on 20m) should...
Last weekend, I was experimenting with a 40 meter dipole in the field. I had built and tuned the antenna at home, but the antenna center...
Assuming there is a little bit of gain on a 5/8 wave vertical, one could presumably use two of these to make a slightly better dipole, and going...
Here is my situation I have an Icom 7300 and a GAP mono band 20 meter vertical dipole. I have done some DXing but would like to have a better...
