Hi Tom,

Yes.

Will I need radials? *

Yes.

Should they be elevated or
can they lie on the ground? *

Yes.

Since the total length of the radiator is
less than a 1/4 wave on eighty meters at say 3.6 MHz will that make
the antenna ineffective on eighty meters?

No.



Second question
5th, actually.
would four of those sixty four foot masts make an
effective forty meter four square.

Yes.

*Yes I realize that it would cost
eight hundred dollars for the masts alone before the cost of
controller, remote, phasing coax, and control cable. *Once again would
radials be required for forty meters.

Yes.

I've only been back in radio for a few years after very long gap so
I'm starting over and finding the learning curve a little steeper than
I remember.

You are still on the level wit the climb to come. *There are a LOT of

Richard
Please share the rest of the story. If we lay out multi length
radials for the middle of each band, say four of them, and feed the
vertical with the auto tuner would we be able to make it work on
eighty, and forty? When we use a half wave end fed zep in the form of
a J pole on two meters we don't need a counterpoise. If I extend this
mast to a half wave on forty will I still need a counterpoise?
