At my new QTH, initially I set up inv U about 80 ft high with 4 125 ft
elevated tuned radials about 10 feet high.
N6BT, who has done a LOT of work on the topic of elevated radials,
told me that 20 ft is a minimum height for 160M. When I raised mine
from about 6 ft to that height, TX signal improved significantly.
But what is the *reason* for it working better. Is it something as
simple as "the currents in the radials aren't loaded as heavily by
something 20 feet away as opposed to 6 feet away" in which case it's a
sort of soft transition, and "going higher" is a matter of diminishing
returns.
