The extra radials help overcome unknown poor-soil conditions, improve bandwidth, and ensure the best performance efficiency possible from the Butternut HF2V antenna. At the base of the antenna is a 4:1 homebrew UNUN and an extensive ground radial network. So, of course, the 80-meter beam worked better. 6 Band Vertical HF Fixed Station 10, 15, 20, 30, 40, and 75 or 80 Meters. Antenna height = 43 feet AGL with the bottom about 3 inches above ground. Having never done that I researched radios, antennas, etc. On 20 meters I have 8 radials, because my prevelant reason for this antenna is 20M DX. They can also be used for fixed applications where there is no ground plane by using included ground radials or wires that screw into the base. Any of the no radial verticals like the Cushcraft R7000 series (which I have personal experience with) or the GAP Titan (I had that one too) and others will work head and shoulders better than the Comet 250B for a similar. Having a 1:1 SWR does not mean you have a good antenna. The ATU can be either preset or automatic and may require a control cable in addition to the coaxial cable feeder 15. Vertical support up to 1. The radials are, essentially a series of four 100′ and six 33′ thin (3/8″) tape measures. Radial wires that leave the base of the vertical antenna are a wonderful way to provide a ground system.
