Hello, I recently connected a OTA antenna in the attic and used a diplexer to connect the OTA and my 2nd TV output. I also installed a diplexer behind the vip622. My problem is that now my 2nd tv gets a snowy picture. I've double checked the diplexer connections several times and I believe I have it connected correctly. I did not have this problem prior to installing the ota antenna. Any ideas or suggestions guys? Thanks!
