[amsat-bb] Re: springtime project

[Jim Jerzycke]

The sep kit that I have consists of some studs that go into the el rotor housing where the bracket was, and some nuts and "muffler clamps" (like 1/2 a u-bolt and clamp) that clamp the rotor housing to the side of the mast. The bottom end of the mast goes into a regular mast mount clamp (GC-038?) turned "upside down", and installed on the top of the az rotor. You could use two of these to mast-mount the az rotor, and then put a mast on the top. I use the sep kit with a G-5500 and an 8' Glen Martin tower. The az rotor goes on the tower shelf, and the mast goes up through the top of the tower and thrust bearing, and I have the el rotor about 6' above the thrust bearing. This gives me enough room to do a full 180 elevation flip with my antennas, and still clear the ground.
I'm going to mount the whole shebang on a little Harbor Freight trailer this year, and tow it down to our Field Day site. Should be much easier than building everything up "from scratch" each year!
73, Jim
