Hello G-5500 Rotor users,

I am mounting my G-5500 AZ and EL rotors together.

Should be OK. Strongest installation has the azimuth positioner on a rotator plate inside the tower, a short mast through a thrust bearing to the elevation positioner with optional Yaesu separation kit. Weakest mounting is the EL unit bolted to the AZ unit with the U channel bracket, and a optional Yaesu mast clamp below the AZ unit. All mounting are OK, depending on loading

The manual pictures show the rotors with the connectors forward and the El rotor axis L-R. The U bracket stipulates this.

Looks like the U channel bracket has only 2 possible mounting positions onto the AZ unit. Though the 4 each bracket to AZ unit mounting holes/bolts are symmetrical on a common bolt circle, the ribs on top of the AZ unit must mate the cut out on the bottom of the U channel, to fit properly. Essentially you have 2 mounting choices, both 180 degrees apart. The manual front page picture, shows the AZ/EL units bolted up and "parked" for a "nice" marketing picture This picture does not show the tapped hole in the U channel. My choice is to put the tapped hole on the same side as the EL connector. Tapped hole is to mount a cable clamp for strain relief. The installation instructions on Page 6 are definitive.

My U bracket is intended to be mounted rotated 90deg.

Does not look like a good choice, either 0 or 180 degrees, NOT 90 degrees. Unless you mill off the interfering ribs in the top of the AZ unit. Why bother ??

The slot in my U bracket runs parallel with the bent up sides. The manual picture shows the slot running perpendicular to the bent up sides.

Not obvious to me. I may have a different picture than you, My manual is part # E12901000 . My picture is accurate in this aspect. The top bib position is indicated by the ribs on the side of the top half of the AZ unit. My picture shows these 2 each (left) side ribs accurately.

The ribs on the top of my AZ rotor run front to back as shown on the picture.

My picture shows the ribs running L-R.

Does anyone else have this situation? If so what is the orientation of the two connectors that works? I would like to put the rotor combination up correct the first time.

Mechanically mount up the U channel to the AZ unit, it will fit 2 ways. Mount the EL unit with the connector on the same side as the tapped hole in the U channel. My choice. Connect test cables and determine where the positioners are actually pointing.

I verify full control range of the AZ 0 thru 360 to 90 degrees in AZ. I verify full control range of Elevation from 0 degrees thru 90 to 180 degrees. Calibrate as necessary.

I park my AZ unit at 0 degrees (full CCW) and the EL unit at 0 degrees also (not 180 degrees). The I put it up on the tower.

You never mention how the AZ unit is mounted , in the tower, on a mast, ??
