Shared Apex Loop over rocky ground
|
Mel - N7GCO - Cheney, WA
My property is extremely rocky. I have tried other loop receive antennas with poor success.
Has anyone experience using a Shared Apex Loop over Rocky ground?

Mel the SAL is ground independent, so that's a very good thing in your case. There are SALs on top of buildings (Kabul for instance) and in the Rocky mountains. It will work fine. What it doesn't like is being near a tower or transmit antenna as it will couple to verticals. Jay, WX0B Jay Terleski Array Solutions 214 954 7140

All else being equal, beverages work best over rocky low conductivity soil, which I have. I replaced my beverages with an SAL30, which performs just as well, or better than 580’ beverages, and it offers more pattern switching choices.
My QTH has just a thin layer of caliche soil over primarily limestone, with a sprinkling of granite. Verticals work very poorly here and even an earth ground for lightning is a challenge. My SAL30 is up on fenceposts to keep it above the deer traffic, and it works very well.
