Cross Country Wireless HF/VHF/UHF Multicoupler
Following on from our successful SDR-4+ HF SDR Receiver we have released a HF/VHF/UHF Multicoupler.
The HF/VHF/UHF Multicoupler allows a single antenna to be shared with up to five receivers. The Multicoupler has in-built lightning surge and over-power protection on the antenna port with over-power protection on each receiver port.
The wide frequency range allows the Multicoupler to be deployed on a variety of signals intelligence or monitoring tasks. It can be used with HF, VHF, UHF or wideband antennas as required.
We now offer three versions of the Multicoupler. The HF/VHF/UHF covers 0.5 to 1350 MHz, the VHF/UHF Multicoupler covers 45 to 1350 MHz and the HF Multicoupler covers 50 kHz to 35 MHz. The new versions have 7th order Constant-K high pass or low pass filters on the RF input to restrict the frequency range for specific monitoring tasks.
