I am wanting to experiment making vertical whips, end fed, for a number of
frequencies
from HF through to UHF and was wondering if someone can point me to a link
with
designs for constructing these.

I want to feed with 50 ohm co-ax for convenience, and I think it basically
has to
resonate at the design frequency, tapped for 50 ohms to feed it and present
a
"high impedance" to the end of the resonant element.

Naturally there will be different designs required for UHF frequencies
compared
to HF frequencies for mechanical considerations and I guess different
matching networks
with different Q's will have pros and cons too..

Anyone with some links / info would be greatly appreciated

Thanks

Nick
