ANTENNA INFORMATION
For radio communications, the antenna is of critical impor-
tance, to maximize your output power and receiver sensitiv-
ity. The transceiver accepts a 50
antenna and a less than
1:1.5 Voltage Standing Wave Ratio (VSWR).
High SWR values not only may damage the transceiver,
but also lead to TVI or BCI problems.
