Thought I might try posting in this forum:
Here's an interesting question hopefully someone can answer! I have a dish 921 receiver with a R/S 2152 antenna and a channel master amp for the OTA channels. For the first year I received all my locals both uhf and vhf using this combo. Recently, last week after I had to reset my 921, I lost my one vhf channel (ABC) but all other channels come in fine? After experimenting with adjusting the antenna, etc, I discovered: when the antenna is connected as should be - all uhf come in great, but no vhf. When I disconnect the transformer from the antenna leading to the amp which leads to the receiver I loose all uhf (as I should) but I then see all my vhf! I'm assuming that is because the amp is attached to the mast that the antenna is installed on. But when I reattach the transformer to the antenna, I loose all vhf and regain all uhf??? I have combated this problem by installing another antenna (R/S 1634) and combining both signals to the receiver. I now have all my locals both uhf and vhf, BUT is this normal?
Could it be a problem with me receiver or the antenna(s)? I really don't want to have two antennas when only one is needed. I'm 19 miles from the towers and all signal strength(s) are 100 - 120. But I can't understand why I need two uhf/vhf antennas to pick up the channels??
Thanks for any advice!
