Mal,
From Dave G3YMC
I notice this series resistance figure was not given in G3KEV's recent
mail, it is by far the
most important characteristic of a transmitting loop.
What's the story, here? The world is waiting! That snow and high winds
shouldn't deprive us. <G> BTW: Maybe if I can get the loop article figures
to you it would help. I'm working on it. If you have a BFC (no!: Big Ferrite
Core) just drop your 50 ohms to ~1 ohm, at the base of the loop, with a 7T
primary. Place your resonating capacitor bank in series with the 1T core
secondary and the loop wire. This amounts to a series resonance connection.
May have concede a few watts to stay within the voltage limits of your mica
capacitors but......... what's a few watts amongst friends; right?
