Have a 322 and cable box. Have the cable output running into the OTA input on the 322, TV1 works just fine, use remote to turn off and cable data runs to the TV. Problem is with TV2 on channel 60, want to include the cable feed into the single RG6 running to a downstairs TV. What would I use to insert the cable feed into the RG going downstairs, splitter or diplexer, since one is VHS-3 and one is UHF-60 could they both share the same RG6 cable and what would I use to get the signals into the cable? First time I have run into this problem....any help would be appreciated...
