There are two push on connectors on the back of the unit for the antennas. I tried an RG6 to push on converter from Radio Shack, no luck near zero sensitivity Is there a special Yamaha push on connector that is required ????? there was one included in the manual drawings, but I don't' have it. There are uni-pole antennas on Amazon that are listed as Yamaha push on, but I would rather use my roof antenna for obvious reasons. Otherwise, how hard is it to replace the TX 1000 push-ons with UHF or RG6 ?
