Description
Required for use with transmit multiplexers, these passive filters provide the additional isolation needed to allow multiple transceivers to be operated on different bands simultaneously on the same antenna. Used individually on mono-band radio and antenna combinations, these filters provide the isolation required in multi-radio contest stations.
Our bandpass filters are available for each of the ten HF Amateur Bands in 200-watt models for the following HF bands of 160, 80, 60, 40, 30, 20, 17, 15, 12, 10 and 6 meters. We can make higher power BPFs by request. Prices are negotiable.
Supplied with standard UHF SO-239 connectors, these HF Transmit Band Pass Filters achieve over 60 dB of out-of-band suppression that virtually eliminates out of band noise and interfering signals. They are designed to provide a sharp roll-off just outside each Amateur band; just below 3.5 MHz and just above 4.0 MHz for the 80-meter filter for example. Our bandpass filters are the first choice of major multi-multi contest stations around the world! They provide the clear benefit of a dramatically lower noise floor for enhanced single-band weak signal reception desired for elite contest and Field Day operations.
After better antennas, these filters are suggested as the most important multi-radio station upgrade by top contest station builders and operators. Our HF Transmit Band Pass Filters simply allow more contacts to be made with worldwide DX stations and DXpeditions.
