I recently moved to a new house with a lot of trees in the backyard. When the installer came he adjusted the dish and checked all the signals and they were pretty good (80s and 90s). Since then, the trees in my backyard have really filled in with leaves and my signal strength has really degraded (mostly 60s and 70s, some 50s) and I'm now getting searching for signal errors sometimes when I watch stuff. I recently removed the extra wires that were coming down from the dish (he replaced the head with a swm but left the 3 extra wires near the dish) but when I checked the signal strength afterwards, it was still very high. Would the trees be the likely culprit or could it be a loose connection?
