T/R BOOSTER ANTENNA PREAMPLIFIER

A Point About Receiving Sensitivity:

The usable sensitivity of any receiving system is determined by the system's first stage Noise Figure. Typically, a 3 to 10 dB feed line loss exists between the antenna and receiver input. This must be added numerically to the receiver unit's attenuation to derive a realistic System Noise Figure. Many good 2 meter receivers have Noise Figures as low as 2 dB. Adding the attenuation of usual antenna/ receiver interconnecting cable can result in as much as a 6 dB Noise Figure. Adding a preamplifier at tlie receiver barely improves the condition.

The Clegg T/R Booster Antenna Preamplifier is designed to establish a receiving Noise Figure where it counts—at the antenna, thereby avoiding feed-iine loss. Relay actuated (in receive mode), 14 to 18 dB gain is provided with a 2-3 dB noise figure.
