1. No _UTC_ rejection here so are we OK for Sunday 15th as part 97s??
2. _Inductor tuning;_ A ferrous metal slug ( powdered iron ) inside of
the coil will lower it's resonance frequency.
A non-ferrous slug ( brass ) will raise the frequency.
3. _R losses_; Forget R losses... Take them or leave them...
If you are at sea or on a salt water shore line then a vertical
wire/tower is #1... Salt water is the _'ground'_, perfect reference @ 630m..
If you live on several square/cubic miles of silica or rock then
forget lossy radial/vario versions... Ugh, too expensive both in bux and
losses...
Inland favorite here @ xsh/17 is for $20 dollars worth of quality
wire and a surplus vacuum variable cap. and you will have a high Q loop ...
Bonus for using this loop is that you get a 'quiet' receive
antenna, typical of loops...
Plus, it is effectively near free space...
Here is proof of performance starter>>
