Shorter vertical antennas, such as Hustler's BTV series, Hy-Gain's AV-14AVQ, AV-18AVQ, and similar antennas with trap or coil loading under 30 ft. in height are good candidates for above-ground mounting. We don't recommend elevating the popular 43 ft. verticals, such as our DXE-MBVE-1.
You'll need two to four each of the 1/4 wave tuned resonant length wires shown below for each band your antenna covers. The 40m radial will work for both 40 and 15 meters.:
- 80m, 67 ft.
- 60m, 44 ft.
- 40m, 33 ft.
- 30m, 23 ft.
- 20m, 16 ft.
- 17m, 13 ft.
- 12m, 9 ft.
- 10m, 8 ft.
