Mag Loop – Part 4 – Initial Values

Did a rough make up of the Mag Loops coupling loop, used RG213 to start with, then tried 7mm copper pipe, both reading were very similar, I still have some tweaking with some other options yet before I decide on which to use on the completed set up.

The VSWR reading have been very encouraging, with the capacitor closed (meshed) it tunes from 2.884MHz to 21.292MHz with the capacitor fully open (unmeshed).

The sample points were taken at the bands PSK frequency (apart from the first and last) and shows that it will tune from 15m to 80m.
