The antenna mast is the part of the antenna that extends from the base. It picks up broadcast radio signals and passes them through the antenna base to the radio. Signs the mast may need replacing include a bent, broken or missing mast, or visible damage after a collision. Weak or noisy reception can also come from the antenna base, the cable or the radio, so diagnose the cause before replacing the mast.
