Here is my map.
My set up is an old uhf/vhf antenna mounted about 25' up. I don't know the model as it came with the house ~25 yrs. It has 10 main elements.
I use 75 ohm cable with a pre amp on the pole. Cable down to a grounding fitting then into the house to the power injector. From there to a channel master distribution amp ( 4 outputs) then throught the house.
My issue: Up unti recently I was using a wineguard AP-8700 pre amp and with that I could point my antenna to the NNW and get the 4 stations from Montreal ( Ch 12,13,6, and 7 which is not on the map). Leaving the antenna pointed this way I could get all my local channels from the "back" of the antenna.
One morning I could get only a few stations and determined that the pre amp had died.
Replaced it with an Antenna Craft 30Db ( AP-8700 no longer available)
Now I can only get Ch 6 out of Montreal and can not get any of my locals from the "back" of the antenna. I have to point it to the east to get them.
Any idea as to what I'm dealing with?
Thanks
