Thankyou Charlie.
I got those Q numbers from

Maybe a decimal point was left out.
Jim,
I thought something was misleading you somewhere.
Be careful with online calculators. The one in the link uses pi out to 39
places (which migh
Just to add a comment on this thread:
I do not use an inductor to match my inverted 'L', just a capacitor from coax
centre/bottom of wire to the radial point. Further I do not use big wide space
'toast-rack' Cs, but tiny ceramic ones rated at 6.3KV which will handle very
decent amounts of powe

Hope this will be of some interest for those using twisted pair instead of

The company I work for is manufacuring all kinds of 75 Ohm / UTP balun adapters
and surge protection units.
The one I am using for my phased biderectional flags is "УПВ-МВ"

info and pictures, but I guess I'll have to take some new photos sometime.
I suppose if you made the elevated radials long, then you co
