Attaches to your radio (or computer), decodes the band data, and provides automatic selection of band specific devices, such as antennas and filters. Responds instantly to your QSY, properly selecting the right antenna, or even the right amplifier.

Designed to connect one input to any one of six outputs. It is useful for antenna selection, filter or stub selection and stack switching. It may be driven directly by a Band Decoder or any selector scheme which grounds one or more of the control lines.

Designed to provide a means to automatically switch an antenna between two radios in a two station environment. Adds flexibility to a Single-Op/Two-Radio, Multi-Single, or Multi-Two station — any antenna not in use is instantly available to either rig.

Band reject coaxial stubs will reduce transmitted harmonics from the final amplifier and reduce fundamental pickup as well. This translates to fewer complaints from the multi-op operators, higher contest scores, and reduced risk of receiver front end damage.
