Hi Stefan
Thank you for your comments on this <crazy> topic
If you remove the counterpoise wire from the PL connector, the screen is floating so there can be
no HV problems. Or do i missunderstand something?
A normal PL-jack may handle 3 kV but 6 kV is not ideal for a longer time i think :-) And you will have 24 kV at 800 W ;-)
You are right. PL connector has no coaxial inside, just inner to vertical element and outer to external screw were radials must be connected
So removing radials there is no risk of HV break. My fear is for the stepper motor which is very close inside the case. If the motor gets burned
I will definetly have to look for another solution
BTW. Those 24kV at 800 W can explain some pictures shown in this reflector ;-)
Will test it at low power first and see what happens. Think I can measure induced voltage on motor coils and this will show the risk of increasing power
I'm still in the process of getting access to the fire extiguish pipe to clamp a wire up to
the antenna. It is not easy, but can be done

I'm using a Ultrabeam V6-40 vertical antenna. My idea is to use it just connecting the inner pin of the PL
to the loading coil, once removed the actual counterpoise wires for HF bands. The inner pin of the PL connects
with the copper-berilium tape which forms the vertical element of the antenna.

Probably the safer way would be to retract the original element completely and use just the fiberglass pole
to support a dedicated wire.
Yes, maybe a better idea.
But you can start at low power, like you did so far and see the improvement over the horizontal loop. The later, if the PL jack burned down, you can search for another solution :-)
