Im
hoping to erect a reasonably large but lightweight temp 60m vertical here
in the near future but need to keep the insulator weight down to the
minimum
- I see toothbrushes have been used in the past at the 400W level
(?) but Im
going to be around that level and concerned over corona _ive
made some
lightweight corona rings up but still concerned. I dont think Im
going to be
able to top cap load so looking like something around 365pF
and perhaps
>3.5mH to resonant
Any pointers and thouughts - yes
its a helium lift
Don't compromise on the section joining the balloon to the wire. I
recall someone hitting the key for the first time and then seeing a puff of
smoke and a kite flying unattached towards the French coast.
I think with a seriously high vertical the high voltage problems will be
minimal. - That's not the case with a small vertical where the end voltages are
huge!
Good luck!
