 Sitco/Triax
PA24-series preamplifiers are designed for critical professional
applications high gain, very low noise figures, high output level,
narrow bandwidth with flat response, tight RF shielding and rugged
mechanical design for high reliability. The preamps are housed in heavy
weatherproof die-cast aluminum housings equipped with hardware for mast
mounting. F connectors and 75-ohm impedance are standard while N
connectors and/or 50-ohm impedance are available.
These preamps require 24 VOLT DC
power (negative ground) which is usually supplied via the output coaxial
cable. As an option, DC may be fed directly into a third cable port in
the preamp housing. DC power may be supplied by the Sitco PS24 power
supply or from any other suitable source.
