PR40—14

THE RAMSEY PR2: THE ULTIMATE BROADBAND PREAMPLIFIER

After you find out how practical a well-built PR40 can be for 440MHz operating, you will be

quite impressed with the “all bands” higher gain (also with very low noise) plus the

convenient AC power supply, BNC I/O connectors and LED ON-OFF indicator of the

Ramsey PR2, available factory-wired. The PR2 uses advanced microwave MMIC for signal-

to-noise figures that are typically 27db (over 4 “S-units”) gain, and only 2-3db of noise

increase. This is a workhorse preamp that’s so easy to try out on many different operating

and experimenting applications.
