Darrel, Great write-up.
Loop antenna info:
The heliax has 1 male and 1 female connector. Looks like right at 30 to
32 feet - roughly 3.5 feet dia with 3 coils.
An online calculator gives 26 pf self capacitance,
7.4MHz 50 pf 2Kv at 4Amps bandwidth ~24 KHz
7MHz 56 pf
4MHz 171 pf 2.5Kv at 12Amps
3.5MHz 236 pf bandwidth ~ 3KHz
Anyhow, just some quick info.
73,
Ray - N5SEZ
