My RX LOOP is VERTICAL with a perimeter length of 850 feet total. I have not noticed any static built up or flashing regardless of wx. The height is 100 feet, however the TX 1/4 wave inv L up at 100

My 40m loop resonated for RX on 500 khz works well but it is a poor performer on 9 khz connected directly to the sound card, I think the card sees it as a short cct because of the Z mismatch. Other a

From Dave G3YMC G3KEV suggests that loops are very inferior to verticals on 136. He may be right, but experience here is not as pessimistic as he would suggest. I use a loop as a means of getting a s

If you're building a loop don't forget that a lot off turns side-by-side constitutes electrically another loop at right angles to the main one, much smaller perhaps but quite enough to knock the notc

The only accurate way to measure loop inductance for an installation is to use an inductance meter. Calculations do not take into account the loop environment like trees and other objects in the vici

What the heck, go with a 1w signal like the US guys use. You will be surprised as to how many stations you can still work if they have a decent receiver and antenna on their end. This way you won't h
