High quality Masthead Preamps with noise figure below 1.5dB and with gain typically between 15dB & 22dB. Individual versions for 2m, or for 4m, or for 6m. RF sensed switching with through power capability in excess of 100W continuous. These Preamps have been in continuous production for over 30 years. Monostable switching circuit with fast attack of about 25milliseconds and with a hang time of typically 500mS so it doesn’t drop out when using SSB between words or syllables, only when you pause for breath. RF sensitivity for reliable switching is about 500mW at the Masthead Unit. Operates from your own external 13.5V bench supply via the Station Box that combines the DC and RF. Consumption is 45mA on receive and 15mA when on transmit. The Station Box is supplied with a 75cm red/black lead to connect to the banch supply. The relay in the Masthead Unit is ON when in receive mode and disengaged in transmit or when power is removed by switching off the Station Box. So it is fail safe. The Masthead Unit has inputs and outputs protected against static and EMC pulses. The DC is fed via the coax feedline and there is both reverse supply protection and forward over-voltage protection. Connectors are SO239 unless otherwise requested. Connection to the antenna is provided by an RG58CU or URM76 coax tail 1.5 metres long which passes into the Masthead box via a compression gland on the underside of the box. The Masthead unit is bolted to a stove enamelled aluminium fixing plate with tabs with holes top and bottom for screw mounting to the antenna mast. Also supplied are two 250mm releasable tie-wraps that can secure the tabs to the support mast. The item “Receive Preamp, Masthead, RF Switched, 2m, or 4m, or 6m.
