My elevated radials are now 24m up but sloping.
Big difference to before where I tried 4m high radials.
I went from a T-vertical to a driven tower with top load as an elevated
groundplane some years ago and that is the best transmit antenna I ever
used.
It is also outstanding on receive. I can hear weak stations with it which
are inaudible on my relatively short 160m long beverage.

Subject: Re: Topband: 160 m inverted L
thanks Rob,
The best I can do in my situation is 10 feet high for the 160M elevated
radials.
A far cry from 50 feet :-(
I will work on maximizing the size of my ground screen under the inverted L.
Hopefully this will increase some of the efficiency lost from the low
elevated radials.
Its tough doing a 160M antenna on a city lot...........
