[Premium-Rx] Antenna question

[GandalfG8 at aol.com]

Hi John,
 
Not sure that "surprised" is the quite right word but given that  you did 
seem to drop off the radar a bit, pleased and relieved to hear  you're still 
ok might be more appropriate:-)
 
regards

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.
