Mounting The G-5500 elevation rotor in any way other than vertical will cause problems as the condensate will not have a way to get out and will ruin the unit.
The coordination with actual direction is easy as it just involves pointing the antenna correctly after mounting the unit any way you do. I am not sure if another drain hole drilled would solve the problem of drainage.
Incidentally if it is a new unit, please do replace all the bolts holding the two halves together with SS Allen Key type bolts as after sitting in the open the regular screws are very difficult to remove with a regular screwdriver- I have had practical experience on this!

Hi,
Beware mounting it at 90 degrees to the vertical. It has a drain hole at the bottom to allow for the drainage of condensation when mounted on the 'U' bracket.

Quick question on mounting a g-5500 elevation router. Does it matter which way you mount it or can you set the controller to know where it is?

If I do this, will I be able to set the antennas somehow so the controller knows where they are or does it determine that on its own?
If I mount it wrong and the controller can not be told where it is (ie. calibrated) then all of my degrees would be off by 90 because I am mounting the elevation portion horizontal instead of vertical.
I hope this question makes sense, but I don't want to assemble it all up high and then findout it doesn't work as planned.
Thanks for any input!

As David already mentioned, you may create drainage problems by mounting your elevation rotor horizontally... if you want to block the existing hole, and drill a new one in the new "bottom" of the rotor, you may be okay,
but "you pays your nickel, you takes your chances".
As far as "setting" the antenna position, the controller doesn't care how the rotor itself is mounted: when the rotor is at the zero degree limit of its travel, you mount your antennas pointing at the horizon, and you have established the zero degree position. Everything is relative from there.

Either my S-Band D/L is not working or the sat never shifted into the new
mode. Comments from the bb.

Hi Bruce,
Well something's working. I just finished the 03:30z pass here. I heard a couple of partial calls on the 2401.200+/- ghz downlink - VE7C?? and another
partial suffix. The pass started with someone with a nice clear signal and a Spanish/Mexican accent. There was a call sign, but I didn't catch it.
However, I was not able to get into the bird myself on 1268.700 +/-. Not even a change in static, even right after I heard an apparent full-quieting "kerchunk". This is with my new and unproven helix antenna, so I have one too many unknowns here to know what the problem is. I did follow the same doppler process on the L-band uplink, and also swept the general vicinity, so that shouldn;t have been the problem, and the pass peaked at about 50 degrees. Nothing back from my uplink.
Anybody else have a go at it?
Greg KO6TH.

Nothing heard on the 05:10z pass. Only a 10 degree pass, but off in a favorable direction (no trees). Downlink carrier was very weak and barely there, if at all. Keying up on 1268 had no effect, as before, though I doubt I would have heard anything even if it had..
Anybody having success?

Greg and I will try to make every pass available on 7/10. I have been praying to the L band gods. We'll see what happens. 10 watts-40feet hardline-40 turn helix. 73 Bob W7LRD Seattle

Hi All I am getting my new 30 ft tower and wish to changeover from RG213 to LMR600 I have, for the Vhf and Uhf cross yagis. Will be installing my masthead preamp too and its going to be convinient to use a short length of thinner coax patch upto the Beams near the AZEL. So any tips , suggestions on the type of thin cable RG-58 or RG-213. Thank you Best 73 Pop VU2POP :o) Vhf & Uhf cross yagis, Masthead preamp for Vhf, AZEL with digital readouts all home brew ;o)
