I had this idea for a vertical antenna taking a 10 foot piece of 2 inch pvc tubing and putting in 6 gauge solid copper wire measure 18 feet coil to half its length put inside of pvc tubing caps on both ends one has a n connector for coax the other has a nut for a 102 inch whip to screw into, would make a 3/4ths wave antenna and work great if you get your swrs low
I have heard that some tried to build a full wave of 36' but I've yet to hear anyone who had much or any success trying it. The 102" stainless steel Whip is actually too short it should be closer to 108" or 9' which is an actual 1/4 wave.
Wow you only have a 20 ft tower, ( 2 ) 10 ft section, I put up 10 sections of tower all by myself, it took me about 2 weeks every 3rd section I guyed it off, the top guy wires ,i put insulators in 2 ft intervals for 20 ft out from the top set of guy wires,, to break up the ground plane effect,, it's a great directional beam..
Wast of time and money with ancient gamma feed wrong spacing Yagi design . This could be a great 10-meter monobander with 2 to 3 more dbd gain and would be so broad banded you could still use it on the chicken band🤣🤣
@@James_Bowie I hear you James, but now they shorten the element length by a third and replace it with loading coils on the ends. Miniature beams with the urban look for us city dwellers 😊
