Power Supply

Clegg's Model Oil Power Supply delivers a highly filtered, regulated source of 13.5 volts for base station mobile radio sets handling up to 6.5 Amperes current Model Oil offers reliable service with any of the popular 5 to 25 watt transceivers and many other devices which operate within the Oil's voltage and current levels.


Output Voltage: 13.5, it 0.5 VDC / Input Voltage: 105-125 VAC, 60 Hz / Maximum Current: 6,5 Amps, DC Regulation: Less than 0,2 volt change: a, for load current from 100 Ma to 6.0 Amperes b. for line voltage from 105 to 125 volts with load current at 6.0 Amperes, Output Ripple: Less than 50 MV RMS at lull load with 110 VAC supply

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.
