Hello, I have a 135 feet L-antenna (70 feet vertical, 65 feet horizontal) for 160 meters with about 20 ¼ wave radials to it. It works well on 160 m and is also resonant with low SWR on 24 Mhz
The pattern for either band resembles a water lily, many small lobes at various elevations around the entire compass, with more power at higher angles. Low SWR on 24 and 28 may indicate loss in the s
Ciao Kari, Try one of the free NEC/MININEC programs on the WB0DGF page: http://www.homestead.com/antennas/files/models.htm I've had good luck with MMANA. For something like an L, it is pretty easy. Y
