[TowerTalk] Inverted L for 160 meters

[jeremy-ca]

That is a blanket statement that doesnt hold much water.

Belrose and others have published also and believe that 12' is adequate on 
160 in many cases. BC band engineers have proven that an elevated system 
delivers the same field strength OR BETTER than a classic 128 buried radials 
at the same site. The FCC has required them to reduce power to that of the 
original proof of performance.

A lot depends on the ground conductivity. With 32 radials 12' high I never 
waited in pileups very long. My ground conductivity is about that of granite 
since it is only a foot or so below ground.
