Tom, 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: http://www.kl7uw.com/sat.htm 73, Ed - KL7UW At 10:38 AM 11/30/2009, Tom wrote: >Thanks for all of the great information.
