ALCON,
Thanks for all your replies! I also contacted DX Engineering, who sells this loop, and he also told me to relocate. He wondered why I had the loop up at 25'. My noise level was always too high, e.g., S2-4. However, that is better than S5-7, which it was on some bands after the gutter installation! He recommended mounting it at least 6' above ground level. Today, I took it down from the roof and located it in the middle of the yard away from the house. I am waiting for the Quickcrete to dry. I also needed to order 100' of coax and rotor cable. I hope to be back in business in a week or so.
V/r,
Vince
