Please specify VHF/FM channel when ordering. The CMA-b and SMCA-b Single Channel Preamplifier Series are professional quality, very low noise, single channel VHF/FM and UHF preamplifiers. The CMA-b is optimized for a single VHF channel or FM band (88-108 MHz), while the SCMA-Ub is optimized for a single UHF channel.
Output test port for uninterrupted service testing
Ideal for all BTY Series Single Channel Antennas
These preamplifiers can accept a wide range of input signal levels and offer excellent gain, making these units ideal for difficult signal areas. The SCMA-Ub has an internal trap that can be factory tuned to a customer specified UHF frequency to prevent overload or intermodulation interference from strong, local channels.
The CMA-b/SCMA-Ub Single Channel Preamplifier Series are housed in a die-cast case. Input, output, and test ports are 75 Ohm, type "F" female connectors. The preamplifiers mount on a 1.5 inch O.D. (max) antenna mast with the supplied mounting hardware. Blonder Tongue PS Series -21 VDC power supplies (available separately) are used to power the preamplifiers through the downleads.
