20 Meter Ground Plane Vertical Antenna
The portable 20m ground plan antenna is a basic wire arrangement with a wire radiator and three radials spaced 120 degrees apart

20m vertical aerial
About ten feet of 22mm copper pipe and about eight feet of 15mm copper pipe

20 meter Vertical with Balun
The balun is rather easy to make you need only a few items. This is a basic balun for a wire antenna, and it worked great for the flagpole

20m vertical antenna
Vertical antennas with a 1/4 or 1/2 wave sizing. Just a happy few build a 5/8 wave vertical antenna. This is remarkable, since the 5/8 has the lowest angle of radiation and has about 1dB more gain compared to 1/4 and 1/2 verticals
