ANTENNA INFORMATION
For radio communications, the antenna is of critical
importance, to maximize your output power and receiver
sensitivity. The transceiver accepts a 50
Ω
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.
