Re: NEC-LIST: horizontal quad loop - matching problem

Good day Chris.

I seem to recall that Marconi or some other company in the UK had a similar
antenna on offer. It was intended for use at near vertical incidence
skywave. This would obviously restrict the frequency to less than roughly
12 MHz. In this case it should not be necessary to raise the antenna more
than about 5 metres above the ground.

Best regards,
Duncan Baker.
