How to Improve the Signal on a Long Cable Run From a Satellite Receiver

So you're looking to get a better picture, sound and overall signal from your satellite dish. Generally, satellite dishes are installed on the roof of homes so there isn't much of a long wire run to get these things connected. However if you live in a particularly wooded area or are on large property, you may need to put your satellite dish elsewhere besides your roof, which could cause signal distortion.

Skill level:

Things you need

  • RG-6 coaxial cable
  • Satellite amplifiers
  • Measuring tape
  • F-connectors for coaxial cable
  • Electrical tape
  • Caulk

  1. 1

    Measure your satellite cable run. These cannot be any longer than 300 feet under any circumstances; the signal will simply not push that far. If your run is longer than 300 feet, you will need to move your dish closer.

  2. 2

    Replace your wire if it has any splits in it. Splitting your cable, even to connect it to just another single wire, will result in signal loss which, coupled with a long run, could be significant. Replace your entire signal run with one single, unsplit cable to solve this problem.

  3. 3

    Replace the coaxial connector ends. Cut off the old ends and attach new F-connectors to replace them. This can be done on your own or by purchasing a coaxial connector kit from a hardware store.

  4. 4

    Weatherproof your connectors. Dust or water can interfere with your signal. Cover both metal coaxial connectors with caulk and allow to dry for one hour. Then completely wrap them up with electrical tape.

  5. 5

    Add a satellite amplifier. These can be added at the dish, at your receiver or on both ends. This should be implemented as a last resort, however, as these can add distortion of their own. Insert the dish end of the coaxial cable into the input on your amplifier. Then attach a coaxial cable to the output of the amplifier. Finally connect that end to the Satellite In port on your satellite receiver.
