[Premium-Rx] Antenna question

Hello Nigel,
Thank you for the kind words. Now living in rural Wales (I guess I should be
GW3PCY) and doing a lot more postal history research than radio, I
nevertheless do read the postings on premium receivers with pleasure.
I still think that the AR-7030 is one of the great receivers (once you
master the menu system) and coupled to a Wellbrook loop it's hard to beat in
our modern noise-ridden environment. I am my own worst enemy, using a
"Homeplug" system as a domestic network, but the loop does a good job of
rejecting the E-field noise. It also helps to be living in rural
surroundings....!
73,
John W.

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.
