on the vehicle roof, with a gain of 2.15 dBi or 5.15 dBi.
■
UHF radios must be installed using an antenna mounted either
centrally on the roof with a gain of 2.15 dBi or 5.65 dBi, or
centrally mounted on the trunk with a gain of 5.65 dBi.
3.
For 25 W radios, the radio must be installed using an externally
mounted antenna with a gain of either 2.15 dBi or 5.15 dBi.
Terminating the
Antenna Cable
