All ComPol, Inc. receivers utilize our patented superhetrodyne SCA demultiplexer.   This technology replaces coil-capacitor filters with ceramic filter elements to guarantee the highest possible fidelity with minimum distortion and out-of-band noise.   Also, this results in minimal aging.  (Patent number 5,023,933)

Note:  The SCA-BA are made in the United States of America.  Most major components are also made in the USA.
