VA6AM Engineering HF Multiplexers
VA6AM Engineering HF Multiplexers are transmit and receive capable Diplexers and Triplexers that are sophisticated RF filtering splitter/combiners. Always used along with monoband HF Band-Pass Filters, they allow multi-transceiver stations to share a single multi-band antenna, simplifying multi-op antenna systems. Supplied with standard UHF Female/SO-239 connectors, HF transmit multiplexers are great for Field Day, contesting and multi-op DXing. Use them anytime you need to operate multiple rigs on one multi-band antenna! Insertion loss is negligible; typically, less than 0.2dB in band! VA6AM Engineering Diplexers and Triplexers provide good levels of isolation between band ports. The multiplexer's main purpose is to provide 50-ohm SO-239 connections for multiple transceivers and balance the impedances for a single 50-ohm feedline to a multi-band antenna. Alternatively, VA6AM Engineering Diplexers and Triplexers can be used to combine multiple low-SWR resonant antennas into a switchless multiband system for a single transceiver.

VA6AM Engineering HF Band-Pass Filters
VA6AM Engineering HF Band-Pass Filters are very high-quality multi-stage inline passive electronic devices designed to specifically limit the transmitting and receiving RF passband to a single Amateur band. They provide the clear benefit of a dramatically lower noise floor for enhanced single-band weak signal reception that is desired by DXers, elite contesting stations and Field Day operations. Used individually on mono-band radio and antenna combinations, these filters provide the isolation required, eliminating image and harmonic RF interference issues for dedicated mono-band operations in multi-radio contesting environments. Required for use with transmit multiplexers, these filters provide the additional isolation needed to allow multiple transceivers to be operated on different bands simultaneously on the same antenna.
