Hi Guys,

I'm sitting at a car dealer today for most of the day so there's lots of time to get lots of reading done. I started on LF Today book which is quite brilliant.

It got me to thinking about the large loop I want to build for SAQ reception the next time it's on. I mentioned this on a recent Western LF Net so apologies if I'm dragging this up again. I tried over Christmas with my active whip and couldn't hear the transmission from my location about an hour south of Nashville.

I already bought several king sticks of 3/4 inch PVC pipe at Lowes. I plan to build a 5 foot diameter loop and use 14 AWG THHN wire. What would be optimal for number of turns? I can resonate with capacitors so it's not a problem for less or more turns. I was thinking something like 20 turns so there will be more wire in the loop then I can resonate with caps to get it to SAQ frequency. I got three way elbow fittings, 90 degree elbows and a few crosses. I intend on having the loop form have about 8 inches of "bar" that I can use to place the turns side by side rather than just jumbled on top of each other. I can place a one turn loop as well to couple the signal into a low noise preamp then into my receiver.
Does that sound reasonable?
Thanks for any comments.
