4-2-2 Fixed Station Match the impedance of the coaxial cable and that of the antenna so that the SWR is less than 1.5 to 10. The protection circuit in the transceiver will activate if the SWR is particularity poor (greater than 3 to 1). High SWR values will cause the transceiver output to drop, and may lead to TVI or BCI reports. A regulated DC power supply (13.8 VDC capable of supplying at less 11 Amperes) is required. 1.
