Since installing my 90 metre perimiter vertical
loop some months ago and resonating it on 136 khz, I have observed that it is
just as prone to QRN/static as the vertical. In my case there is no advantage
using the loop as far as noise is concerned. Being located out in the country I
do not suffer from any local environmental noise only the usual summer time
static and this is just as bad whether I use the vertical or loop. The loop is
vertical and used so far only for RX on LF, direction E/W.
It will be interesting to compare signals from the
USA between the Loop and the Vertical.
Using the loop to receive the recent Russian
activity worked very well, with signals solid at all times day and night,
both aural and visual S6 to S9 and over.
