The first picture
shows the Motorola MSF5000 repeater with the front door off. The
black panel on top of the cabinet is the duplexer, the grey panel
above it holds the pre-amp and pre-selector cavities.
The repeater is putting around 56 watts out of the duplexer. 7/8"
Heliax feeds a Sinclair antenna with approximately 8 dBd gain. Input
frequency is 902.3375 MHz, output is 927.3375 MHz, 151.4 Hz PL in
and out.
The next picture shows the repeater with the door on and repeater
owner Ken, WA6OSB. In the upper right of the picture is a PolyPhaser
for lightning protection.
The repeater was installed in the SANDRA site on Mt. Otay on the
4th of July 2004. We dragged it the final few hundred feet up the
hill on a large-wheeled dolly. Invaluable assistance in the repeater
installation was provided by John, K6RLV; Alex, WB6DTR; Stogie,
KG6JCW and Erich, W6LKK.
