The SCMA and CMA-b Single Channel Preamplifier Series are professional quality, very low noise, single channel VHF/FM and UHF preamplifiers. Both the SCMA and CMA-b are optimized for a single VHF channel or FM Band (88-108 MHz), while the SCMA-Ub is optimized for a single UHF channel. 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 SCMA/CMA-b Single Channel Preamplifier Series are housed in a diecast case. Input, output, and test ports are 75 ohm, type “F” female connectors. A 5/8″ entry adapter is supplied on the SCMA Series (only) to allow use of a 0.500 or 0.750 aluminum cable connector. 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.
