[Premium-Rx] Antenna question

[Michael O'Beirne]

A propos John's offering tonight, I have a Wellbrook Loop mounted three 
floors up on the roof and I can attest to its excellence right down to VLF. 
If it does intermodulate, it certainly does not show it.

By way of example the strongest station here on LW is Radio 4 on 198 kHz 
which booms in at around 10 - 15mV PD, and Radio 5 Live is a litle stronger 
on 909kHz, yet weak signals just 9kHz away are not affected.

It picks up less absolute RF than a long wire but a hell of a lot less 
noise, so the S+n/n is excellent.

The Loop also exhibits about 30dB directivity when exactly broadside and 
that is useful if you mount it on a rotator.
