As of December I have had my OTA up an running in Beamsville, just below the escarpment east of Mountain Ave. I am using a DB8E, Channel Master CM-778 Pre Amp approx 65 feet of RG6 to a CM 4 port distribution amp serving 4 TV's.
When I installed my system I stuck it on my rear deck with the intention of putting it on the roof, in the spring (now). It was directly behind my house about 15 feet off the ground facing east.( my house completely blocked it from the west. I was able to pull in about 29 channels consistently with great quality pictures. It included all the Buffalo channels, pretty well everything off the CN Tower, CFTO, Global and City. I was quite happy, but...I could not get CHCH. I figured it was due to the back of the antenna being about 2 feet away from the house. I had one panel pointing towards Buffalo, about 123 degrees and the other about 90 degrees or West. I was able to get CHCH in if I messed with the antenna but lost most of the other channels.
So fast forward to this week. I installed my antennae on a tripod mount on my roof, at least 35 feet above ground level. I can pretty well see the CN tower. There is no obstructions towards Buffalo except the escarpment way off in the distance. I know from the TV Fool report reception in my area is iffy, Beamsville is in a bit of a depression. I end up using about 65 feet of RG 6. I fire up the system, and to my surprise, reception is worse. I am fighting to get 20 channels, with the antennae pointed in the same direction with the same configuration. I can get CHCH if I adjust the antennae but lose most of the other channels. I also tried disconnecting my Pre Amp thinking my signals may be too strong but it was worse.
So I am looking at getting some advice from some of the Wizards here, who have forgot more about this stuff than I know. These are the few things I have been thinking....
Now that I have the Antenna on the roof, are my signals too strong and are blocking other signals in the same direction?
Am I expecting too much of one antennae in a fixed position to cover approximately 220 degrees of various signals?
It seems when I turn the panels for example 90 degrees to each other the reception gets worse.
So I am looking at options.....what do you think?.... add a rotor? Add a DB2E single panel?
I have saved my TV Fool report and provided a link. I have screen shots but can't seem to insert the photo, U/K why.
If I have done it wrong just give me a shout an I will try and fix it.
Thanks for your help.....Steve
