TX / RX Antennas

The TNC jack marked “RCV” is for the receive antenna. The TNC jack marked “TRAN” is for the transmit antenna. The base station will come with two ½ wave antennas. Always match the color dot on the base station with the colored band on the antenna.

2W Intercom Ports

The base station has the ability to interface with up to six lines of 2-wire intercom. Intercoms 1 to 4 are available in two loca- tions, the XLR ports and the D-sub loop thru connectors. In- tercoms 5 and 6 are available only at the D-sub. See Figure 6-3 for the intercom assignments of the XLR and D-sub con- nectors. The female and male connectors are paralleled to- gether. For a description of how to set up the 2W port refer to Intercom Settings in this Section.
