Missing Antenna Radiator

If the antenna cap is missing or if there is a cap without a radiator, install a new antenna
cap with a radiator. If the radiator looks obviously damaged (i.e., dents or corrosion) or
the slot in the radiator has a significantly different shape, then install a new antenna cap
with the correct radiator.
If no antenna or no radiator is installed, the antenna gain will be degraded by more than
25 dB.
