HD7697P Cartridge Housing

[tjw]

My HD7697P has only one 75 Ohm downlead for UHF/VHF. The manual indicates that it's possible to have a cartridge housing that has two 75 Ohm downleads (one UHF and one VHF). Is it possible to buy this split UHF/VHF cartridge and just swap it into my antenna? If so, how much does it cost?

Basically, I want to stack an additional UHF antenna pointing in the opposite direction as my HD7697P for UHF, but I'm afraid the VHF loss in doing this may be too much to bear so I would like to eliminate VHF loss by joining the VHF part of the antenna with a UHF-VHF joiner after the two UHF antennas are joined.

The cartridge board/housing (CB-8269) used with a HD7697P antenna is designed to combine the VHF signal and UHF signal from the antenna onto a single coax cable using 2 VHF clips and 2 UHF clips that make contact with the 2 VHF phasing lines and the 2 UHF phasing lines. The CB-1469 is used with a UHF antenna such as the HD9095P or HD9075P only has 2 clips to make contact with the antenna and allows you to combine a separate VHF input signal to the UHF signal from the antenna signal via the separate 75 ohm VHF input circuit connection. There are no VHF clips on the CB-1469 to make contact with the VHF phasing lines in the HD7697P antenna. Winegard does not have a cartridge board/housing that will allow you to separate the VHF and UHF signals from an antenna to separate leads.

The only way you can separate the VHF and UHF signal from your HD7697P antenna is to use a separate UHF/VHF separator/joiner to separate your VHF and UHF signals and another to combine your VHF signal back together with your UHF signals after you have combined your two UHF antennas.

Thanks for the information about the cartridge compatibility.

I hadn't considered this as an option. I have a feeling that it may be very hard to get much of a stacking advantage using all of these combiners though. I will keep trying to find a Jointenna for channel 38 I guess.
