That is the old standard for satellite operation
when we had MEO and HEO sats to work.
Since I have my old antennas that is what I am putting up:
145: 7-element M2 yagi, mgf-1302 preamp, TR relay
at tower, 50w FT-847 (about 20w max at
antenna). The KLM-22C will replace this antenna once I have re-assembled.
435: M2-436CP42, 50w PA at tower, mgf-1302
preamp, with TR relay to support either mode-B or J
1268: 45-element loop-yagi, 15w Tx converter
(DEMI 1268/144) (drives with 2w on 144)
2400: 33-inch dish, helix feed, MK232 LNA, two
Drake converters (123 & 435 IF's)
Since these are all narrow beamwidth antennas
auto-tracking is desirable. I am using the B5400
az-el rotator with Unitrac-2000, SATPC32
I have all the antennasand the 1268 unit mounted
. Dish is next then we swing it all up into
place and install the outdoor box with 12v PS and electronics:
