Thank you for feedback John.
Some clarifications: Winegard AP-8700 has two FM traps, a fixed and a variable one. I haven't altered factory settings, just made sure that the fix FM trap is on. Haven't played with the variable at all.
The coax is grounded to a grounding block (actually a combination of grounding block and lightning arrestor - TII 212 Broadband Cable TV Lightning Surge Protector), connected to an 8-foot copper clad rod and bonded to the house service ground.
The splitter is a Channel Master 4 way splitter.
Interesting fact: prior to the pre-amp installation and with no splitter I was able to get Fox quite good (at 55-65 out of 100) with very weak ABC (10 out of 100). Of course I have tried many different aiming positions since then and can't seem to remember the exact position.
Aiming the antenna seems to be the pain point: I have tried 181 magnetic degrees (everything is an approximation anyway, how can I be absolutely sure?) and I don't seem to get the most out of it. The most channels and at the farthest distance are at 161 magnetic degrees.
To be honest with you, I've struggled to understand why I should be aiming the antenna at 181 magnetic. 181 magnetic and above yields only three channels: CHCH-DT on 11.1 (green zone), CITS-DT on 36.1 (yellow zone) and WNYB-DT on 26.1 (red zone) - I'm not particularly keen with any of these.
How would this position help with NBC on 2.1 (157 magnetic)? Would this position help with following channels at 161 magnetic: PBS on 17.1 and Fox on 29.1 at 64 miles? CBS on 4.1 at 93 miles? ABC on 7.1 at 95 miles?
Thank you!
