NEW PRODUCT LINE
(Available 9/1/2026)
KD2C SDR Products will be offering a complete new line of professional grade products geared for the SDR, Scanner and Receiver market.
The new products will include 2, 4, 8, and 16 port Amplified Multicouplers, Pre-Amps, Bias-T’s, 2 & 4 port Passive Splitter/Combiners and more.
The Multicouplers are 50 Ohm and designed to maintain the input signal level across all output ports.
All Multicouplers are custom built and come in a VHF/UHF and HF version. All have a bandpass filter to accommodate the 20MHz to 1GHZ rang for the VHF/UHF model and 500kHz to 30 MHz HF model. Special bandpass filters can be incorporated upon request.
The Pre-Amps are 50 Ohm and are also custom built to order. They provide 20dB gain for 20MHz to 1GHz bandwidth. All Pre-Amps incorporate a RF Limiter circuit to protect from signal overload and antenna static buildup. All have a bandpass filter to accommodate the 20MHz to 1GHZ range. Special bandpass filters can be incorporated upon request.
All devices come with high quality Amphenol input and output connectors. Inputs are available with N, BNC or SO-239 female connectors. All outputs are BNC. All cases are aluminum alloy to resist corrosion.
