For the past five years I have tested three Channel Master antennas for HDTV reception. I'm using a 50' steel tower with a 7775 Channel Master preamp, a 9521a channel master rotor and RG-11 downlead [to reduce line loss].
The first antenna was a 4248 channel master antenna and I was able to pick-up all Rochester NY channels, Buffalo channels recieved were channels 2,4,29,43 none from Syracuse.
I then installed a 4228 channel master and recieve channels 68 and 24 from Syracuse and intermitently channels 3,5,9.
My neighbor then gave me a new Channel Master 4250 which I gave a try signal strength was the same as the 4228 the only differance is that the 4250 was extremely directional and I thought that would help me recieve channel 5 out of Toronto because the physical channel for CBLT 5 is channel 20 and in Rochester the PBS analog channel is channel 21 I am experinceing co-channel interferance. The 4250 did not correct the problem so I took it down and put back the 4228. This is an experiment in progress, some channels are low power, some experiance co-channel interferance.
I always scan for digital channels between 6:00am-8:00am I have recieved digital channels as far away as Watertown NY. I used to recieve analog channel 27 Global from the CN tower but since Fox network in Rochester started broadcasting digitally on channel 28 it has destroyed channel 27.
I am no longer able to recieve any Canadian Broadcasts and its a shame because I always respect other peoples or Countys points of veiw, especially politics. I look forward to being able to recieve Free canadian broadcasts in the future.
