Hi,
I am using a channel master amplifier. My antenna is on my roof and the cable goes to my basement and from there I have four cables going to 4 tv's. I did try the Insignia in my kitchen and I didn't get channel 13 however when I put the Insignia back in my living room I got channel 13. In my kitchen I have a Zenith unit DTT901
DTV converter and I can't get ch. 13 at all. Upstairs I have a Sony connected to a Digital Stream unit, I am getting a new channel 3 on the second floor which I cannot get on my 2 tv's on my first floor but all the other channels are the same channels. Why am I getting different channels on different tv's is for the moment a mystery. A friend of mine loaned me a Radio Shack
HDTV antenna that looks like a flying saucer and it seemed worse because I got less channels than I got with without Radio Shack antenna connected to the different tv's. I have to be getting a strong signal especially up on my second floor because I am getting one additional tv channel.
I would like to be able to get same amount of channels on all tv's if possible. I hope you will be able to help me.
Thanks.
