If your TV uses a cable or satellite box, you may need to contact your service provider for further assistance in improving the signal strength.

How do I stop my antenna from interference?

A Ferrite core cord noise suppressor can also help. It filters out high-frequency noise or EM interference in the power cord or cable. Just place it around the cable, and small magnets in the suppressor remove the interference. Ferrite cores can be placed on multiple cables to reduce interference.

Why is TV reception better at night?

Television signals travel best in the daytime because they are reflected off of the ionosphere. However, as the Earth rotates, signals are scattered in all directions. At night, when the Earth is facing away from the sun, these scattered signals are lessened and television reception is better.

Why is my TV glitching?

Causes of Glitchy TV Screen

Does my antenna need an amplifier?

You shouldn't need an amplifier with a 20 foot coaxial cable. However, sometimes an amplifier is necessary to overcome signal loss related to splitters and junctions. I would not recommend adding an amplifier if you don't need one.

Can I combine two TV antennas?

Combiners (which cost about $20) merge the two sets of signals into a single stream of TV. Using a combiner is as easy as plugging the coax cables from the two antennas into the combiner device and then using a third coax cable from the combiner to connect to the Tablo OTA DVR or TV. Easy peasy!
