Using Existing Cable Units for Your OTA Television Antenna

I have the same situation as with Helena. Mom of four boys and just tried to make ends meet got rid of cable expense. Interested in the DB2 with the J post to be located in the attic. My house was pre-wired so cable company just came in and connected service. Now that my service is gone…can I use that same box on the side of my house where they hooked up their cable and connect it to the DB2 up in the attic? There are 8 cable outlets in the house…would it still work and what kind of amplifier should I use? From Mariel in Richmond, VA

Hi Mariel,

Since it sounds like you already have coaxial cable running through the house it might be worth it to see if there is or is not a single network of coax inside the house. If it is not a single network, you may not receive reception on all of your TVs.

Also, when using the leftover cables you must ensure all of the distribution items installed by the Dish company are removed such as splitters and diplexers because they could interfere with your reception.

Amplifiers are sometimes necessary to overcome signal loss related to splitters and junctions. Remember that an amplifier does not create a signal. It will only enhance a signal that is already there, but may be weak when split to different televisions. Here are some previous blog posts that might help.
