[TowerTalk] Number of Radials and what lengths vertical 80m up.

[john at kk9a.com]

I am not aware of the many schools of thought of radial design that W1JCW
referred to. For a multiband SteppIR I think ground radials would be better
than elevated since they do not need to be resonant. There are many methods
to installing them, I installed some in last month in 95 degree heat in soil
that is hard clay and it was not fun. I searched for other ways to install
them and I found this interesting method:

Why would someone use HK1H's option 3?

John,


There are three options.


1.- Ground radials. Minimum about 30. Any lenght (random lenghts)..


2.- Elevated radial. Minimum 2 per band, best 4 per band. Exactly 1/4 Lambda

(same size as a dipole).


3.- Elevated radials over ground radials. Both above together.

Putting a steppIR Big IR 80m - 6m.

What length of radials should I put on and what lengths?

Have room for several and wanted to see a few schools of thought of lengths
and 
how many.

Thanks
