power source when operating in a vehicle. The plug
may cause voltage drops and ignition noise may be su-
perimposed onto transmit or receive audio.
ANTENNA INFORMATION
For radio communications, the antenna is of critical impor-
tance, to maximize your output power and receiver sensi-
tivity. The transceiver accepts a 50
Ω
antenna and less
than 1:1.5 of Voltage Standing Wave Ratio (VSWR). High
SWR values not only may damage the transceiver but also
lead to TVI or BCI problems.
