The new BEKO HPP-144 & HPP-432 preamplifiers are the ideal addition for all users who desire to run their amplifiers at the maximum full power levels.

 

These preamplifiers set a new standard featuring 2.5 kW thru power ratings, high rel. relays that contain ceramic and PTFE linings.  They also include several protection circuits.

 

Designed by HA8ET, they provide noise figures of <0.5 dB (typ.), adjustable gain (14 -20 dB.) and high level performance with an input IP3 of 22 dBm.

 

Voltage can be feed through the coaxial cable or via a separate voltage feed connected to the SO239 socket.

 

These preamplifiers are narrow-band and include filters to reject FM broadcast as well as other services.

 

Because of their High Power ratings they are most suitable for Weak Signal, Scatter, EME and all the new digital modes.

Also available (Special order) with 7/16 DIN connectors at additional cost.
