The Comet CF-530 is an antenna switch that is also called a duplexer or antenna switch. With this duplexer for 50MHz / 430MHz you can simultaneously transmit and receive from both 50MHz (or HF bands) and 144 Mhz (or 430MHz band). The CF-530 is equipped with 2 PL-259 output connectors and a SO239 input connector.
The high quality filters in the Comet CF-530 ensure that TVI is prevented at the same time. The isolation between the two connectors is more than 45dB, in case you use the CF-530 for one frequency, the other connector can remain open, but it is advised to place a dummy load on the connector that remains open.
