I just moved my 622 to the basement and now I'm also having problems with the TV2 remote receiving the signals. I tried positioning the antenna higher using coax but it didn't help much. I would like to try the splitter solution but need more info. My 622 already is using a diplexer on both ends to send the backfeed. Can I still use a splitter to move the antenna upstairs? What type of splitter do I need to purchase? Thanks!
