Can I Combine OTA HDTV Antenna with Satellite Dish on One Coax Cable?

By Chris Boylan

Question:

Dear Expert,

Can I split my satellite cable line box on my roof to add a HDTV antenna?  Will this work through the same coax cable?

Thanks,

-Nino R.

Answer:

Hi, Nino,

You can combine satellite and OTA (broadcast) HDTV antenna signals on one line through the use of 2 diplexers (one to combine them and another to separate them back out). You cannot use a standard splitter, it has to be a diplexer.

Here's one that should work with current DIRECTV or DISH Network signals:

Hope that helps.
