#1. Get a different cell provider. Find out who is using those towers.
#2. Get a splicing kit for the fiber. ;^)
I looked around and found who had use of those towers---
went to their store, told them my previous issues, was given a chart that show high signals in my area, I'm wide open in a valley. With 50 years of RF and associated technology--I was certain (line of sight) if I could see the towers they'd hit my phone.
They gave me gold plated guarantee---I brought it back in two days --nada , nada, nothing--not even 911. They check with the home company--redfaced they came back and said we have problems in that area. No if I chose to ONLY use my cell phone 30 ft from my rear door STRONG signal. I knoW RF patterns have holes, and they are not all charted and having had this in my professional life--I was pretty sure --a few feet in any direction would solve the problem--except that's not in my home.
My ladder isn't long enough to reach the Fibre. I talked to VP of engineering of ShenValley cable and offered to pay for poles and cable--no takers--it's only for high populated housing developments
