Intellitron DU-1202 1.8-225MHz / 350-540MHz Duplexer 500w

The Intellitron DU-1202 is a duplexer designed to enable the connection of two transceivers to a single antenna or the connection of two antennas to a single transceiver. This device operates in two frequency ranges: 1.8-225MHz and 350-540MHz, making it versatile for a variety of radio communication applications. It is rated for a power handling capacity of 500 Watts.

Duplexers are commonly used in scenarios where multiple transceivers need to share a common antenna, or when a single transceiver needs to switch between two antennas for transmission and reception in different frequency bands. They help prevent interference between the transceivers and ensure efficient use of a shared antenna system.

In the case of the DU-1202, it allows you to connect two transceivers to a single antenna, or alternatively, connect two antennas to a single transceiver. This can be useful in situations where space or antenna mounting options are limited, and it enables more flexible operation in diverse frequency ranges.

When using a duplexer, it’s important to ensure that the transceivers or antennas being connected are within the specified frequency ranges supported by the duplexer. Additionally, proper tuning and adjustment may be required to achieve optimal performance.
