I use the K9AY loop and one side of the loop is only 2 meters from
one elevated radial.
1. My inverted L is grounded during receive for noise reduction
(used info from ON4UN's book) and
2. When it becomes deaf or looses directivity, I have lost my ground
due to excessive dry WX.
Lots of watering of the ground and cleaning the ground rod restores
the operation of my AY loop.
