But what worries me, the very thin coaxial inner conductor is in
series with the main loop conductor. It may have a loss resistance
several times greater than the large diameter main loop. You could
be losing a lot of decibels.

=====================================
Lee,

If you cut the length of coax into, say, 7 equal lengths and connected
them in parallel you will have a capacitor of the same value but with
a loss resistance only 1/7th of the single length.

More compact too. 6 fit very nicely round 1. Bundle them up in a
plastic bag to keep off the rain.

RG8 / UR213 would be more convenient i should think Reg if i were running a
bit more QRO......

I`ll try that Reg..... i have an old QRP atu with air spaced variables
around 350pf with slow motion drive i could use on a more ambitious project
a little later....good for 100watts or so SSB...Yes?
