GeoSatPro 90cm dish elevation setting?

Radioguy41 · Aug 9, 2015

My new GeoSatPro 90cm dish arrived. I put it together and have run into an issue that I'm sure has a simple solution but I'm not seeing it. The assembly instructions show an elevation pointer visible through the slot but I'm not seeing any. What am I missing or is there an alternative way to set the elevation accurately?

Just use the edge of the metal you see though the "window".

Mine is calibrated 50 deg to 90 deg and does not have the mark either.

So mine seems to be sat elevation + dish offset angle - ~4 degrees.
For 97W at 42 deg elevation:

Your eyes must be getting old or you may need a little more light! LOL! The elevation is currently set at approximately 38 degrees.

On the A-scale side the elevation scale, the white color flat edge pointer is even with the left edge of the elevation nut/washer. On the B-scale side, the white flat edge is even with the right edge of the elevation nut/washer.

Does your not have numbers on the "A" side?

No mine has a B. You can see in my photo.

Fred, walk around to the other side of the dish.... LOL!!!

Scale A is on the left, scale B is on the right. Maybe also show a wider shot that shows the entire elevation bracket with the clamp. Use the correct hole in the clamp when assembling?

DUHH! Yes it has an A side that reads correct elevation. The problem with being in the woods is that side of the dish is in the bushes and not really easily accessible. I have to put the dishes in the trees on one side of the property to be able to see over the trees on the other.Thanks for pointing this out!

All I'm seeing through the slot is daylight and the back of the nut on the other side. What is clear is that the illustration in the assembly sheet is misleading in that it shows the pointer to be at least 1/8", or more, out in front of the nut while in fact it is covered by the nut. No big deal as long as there's an easy workaround. I'll use the edge of the nut and see how it goes.

I think I see a little sliver of the metal, anyhow degrees should be read just about here?

Remove the nut and paint all the visible metal on that side with some white paint?

Titanium · Aug 9, 2015

Workaround? :helpsign

This is about the best advice I can come up with.... LOL!!!!

Your photo of the clamp shows white paint on the edges that will show through either the A-scale or the B-scale when assembled. Whoever assembled the dish had to stare through the elevation scales on either side of the bracket at the white paint marks as the carriage bolts were placed in the square hole touching white paint and stare again when threading the washer nuts onto the carriage bolts.....

I don't remember mine being hidden behind the nuts... did the size change at some point? (Not going to check right now because it would require a ladder!)

Many years ago the dish was shipped with separate nuts and washers. About 5+ years ago, the hardware was shifted to the combo nut/serrated washer. The diameter of the integrated washer is slightly larger, but I don't recall a time where the white line was visible beyond the edge of the washer. I believe that it has has always been about flush with the washer and I had drawn the diagram to exaggerate the mark visibility so installers would at least look in the right area and likely see it.

Frankly, I am a little excited as this may the first time that my drawing has been studied so carefully and been discussed in 11 years and 50,000+ dishes! LOL!!!

The dish is mounted and set so as soon as I finish running the coax inside the house I'll be able to fire it up and see if it is, in fact, on the mark. I always assume assembly instructions to be accurate, not exaggerated.

Temp straps holding the coax. They'll be replaced.

Titanium · Aug 9, 2015

Looking nice!

Radioguy41 · Aug 9, 2015

Thanks. I'm getting anxious to fire it up. I've been piggy-backing on my C-band dish for 7 years now and that gets tiresome after a while. It'll be a real pleasure to have everything controlled by a single receiver.

KE4EST · Aug 9, 2015

Yes, looks very good. Nothing wrong with zip-ties.

It took all morning but I finally got the coax to the other end of the house and up through the floor. Since my longitude is 76 it's pretty much a lost cause as far as a true south satellite. What I did was point the C-band piggy backed dish to SES2 (87W), tuned in a channel and shut it down and disconnected everything. I then connected the new coax to the MicroHD, turned it on, reset it to USALS, and told it to go to SES2. By George I've got a picture so I rescanned SES2 and it found even a couple more than I had using the C-band dish. Next step is to fine tune the dish but it's been pouring down rain all day so that'll have to wait.

On these Ku dishes, does it make much of a difference if you slide the LNB front or back in the bracket. Is there a sweet spot similar to a prime focus dish?

Good thinking on having the receiver setup. Very nice you got it at startup.

On my 1.2m dishes, there is a better Q on the receiver with the LNBF positioned back away from the dish. Maybe adjust this some with your tuneup.
