Metal buildings create challenges for television and radio reception. Attempting to mount and orient an antenna in a metal structure is often an exercise in futility, with the metal structure reflecting signals away from the antenna. Once the antenna is placed on a suitable support away from the building, however, connecting the antenna's coaxial cable to an AM/FM receiver, or tuner, is the simple part.

Skill level:

Things you need

  • RG-6 coaxial cable

  1. 1

    Access the back of the AM/FM receiver. Look for a small, threaded cylindrical post with a small hole in the middle.

  2. 2

    Screw an RG-6 coaxial cable of sufficient length clockwise from a wall plate that has a threaded post that matches the one on the receiver.

  3. 3

    Connect the other end of the coaxial cable to the receiver's coaxial input. It is typically labelled "FM," "ANT" or "RF."

  4. 4

    Turn on the receiver. Tune the receiver to a radio station that you know has a strong signal to confirm signal reception from the metal building.

Tips and warnings

  • Using a powered amplifier boosts a radio's signal. It sits in-line with the coaxial cable feed-line from the antenna.
  • Use an adjustable amplifier to decrease a radio signal that is too strong.
