Hi Piotr

Yes, the WF load the tower and if you use the same tower to transmits, like
I do,  the voltage can me over 10KV. Also the transformer and resistor
should stand 900 joules or 1 KW for one second, 100 for 10 seconds, you font
want to burn the phasing system, and replaced it any time you have a
thunderstorm nearby.

The logistic to get the antenna at the tower most of the time  cost more
than the antenna itself, repeating the installation several times a year is
not a good idea.

JC

I've noticed use of teflon tubing in a Flag family transformers.
Apart from low losses: is there another reason to use teflon coated wires?
