As others have noted two radials is a minimum. They should be used in
balanced numbers, pairs.
You also may benefit to have one radial in each direction you wish to work,
as that increases the signals from that direction when you have only one
radial in that direction. Pairing radials is
The nice thing about the Ten Tec kit, is that it can be easily converted to
an L network tuner, if you switch the point where the pick up circuit
monitors current, and substitute a coax jack for the connection in one
original hole. That way, it can be converted back to artificial ground
service
Ya' make my drool, Jim, thinking that I'd have a yard nearly big enough to
stick up a 60 or 120 foot full-size vertical plus a bunch of 60 to 120 foot
radials around the base for 80 or 160 meters. I even have to dream of having
enough room to do that on 40 at some future date.

Jim,
I will agree with you wholeheartedly, except for the RF Ground part ---
In reality, RF ground has only to do with a zero impedance reference for RF
at the frequency of operation. It can actually be up in the air (example -
at the midpoint of a dipole, normally the dipole feedpoint), or at
Did you try starting out with the BFO settings suggested in the SSB module

It sounds like you might have the BFO on the wrong sideband for the low

Unless I am mistaken, there is supposedly a schematic available for the

Got one last year to use on a vertical in conjunction with a standard tuner and
now as a conterpoise to a LW antenna. It resolved effectively a high SWR

It consists of a LC network which creates a low impedance path to a standard

When the email you send is received by the reflector software, that

A crude analogy would be how the ionosphere reflects HF radio signals.
Hope that helps :-)

I currently have the antenna attached to a good earth ground and will add
radials for each band per your suggestion. I understand that radials can
significantly improve the efficiency of monopole antennas. Should I try to
add more then one radial per band?

For your long wire situation, one set should be sufficient to provide
adequate RF grounding at your tuner loaction - or if you prefer you could
use an artificial ground instead (see recent discussion on the reflector).
