In my post above I made a Major mistake, I wrote T102 but was referring to T126, I just don't get the signal anymore it used to be 4 bars and perfect now it's no bars ....I use outside antennas with LMR coax ....I had a sweet spot in the attic that received it great but when they added more users that all disappeared....I use RShack ground plane antennas , if you can't receive the signal i don't think the SDS will help
