Need some help - 8 foot Unimesh install

[comfortably_numb]

Pole is mounted and level, dish is mounted on the pole. Actuator is attached but not bolted down. Slowly moved dish across the arc but haven't been able to lock anything. What are we doing wrong?

Did you grease it with green hatch chilies?

 

[primestar31]

The very FIRST thing you MUST get perfect: Aligning motorized dish without Zenith sat

OH, and are you sure the lnbf is parallel to the dish, and at the proper focal distance?

Read through my old thread starting at post 27, there's plenty to learn (in my case at the time, re-learn stuff I had forgotten) I'll take "Name that satellite" for $500 please! HELP!

This wouldn't be a cause for your dish not receiving, but my instructions say your jack is on the wrong tab on the mount. Since you're west of Denver, the jack should go to the other tab.

Added: Forget this. I never realized Albuquerque is almost due south of Denver. I thought it was further west.

Elevation beam facing S, elevation setting per location latitude. If the dish was obtained fairly locally and this wasn't moved, it should already be close. I notice there is apparently no declination adjustment, which is pretty crude- there may be some amount of declination built in (extra length of metal on the top pivot vs. the bottom) but I cannot tell. This could affect ability to line up on the full arc once start getting signals

Declination bolt is right there on the bottom, photo #2 in post #1

Here's the manual, if you haven't already found it. U

We're seeing scrambled feeds 4060 H 30000

What satellite is this?

I see it there now. Some cheap dishes actually didn't have one

Also 4060 H 30000

[Mr Tony]

121w

Galaxy 31 at 121.0°W - LyngSat

 

[Brct203]

Also 4060 H 30000

Shepherd's Chapel

looks like that would be 121W

Shepherd's Chapel is ITC on 121W. But it's 4060 V 30000.

could be that his LNBF is turned 90 degrees

It's starting to look like a headend out here

We had success tuning a lot of feeds on 117 and 121, but nothing east of that.

So we have a lot of work to do, but we have a good start.

Perhaps this will help.

Thanks FTA4PA, I was going to suggest that, but couldn't find my copy. Good info.

For me, the first target would be to have your setup aligned to true south, and/or receive a satellite near true south.
I'm not sure what you have done already, regarding that?
And how have you set your axis elevation angle, and your dish declination offset angle?

When you have found a satellite near south, the true south fineadjustment can be checked with the bottom picture of this pdf: www.repentnow.com/adjustsatellitearc2.pdf

After the true south aiming is correct, the combination of elevation/declination angles towards the extremes can be checked; see the first two pictures of the pdf.

(Because the fineadjustment of a dish is usually done when a true south satellite is already found, I prefer fine-adjustment drawings with a due south satellite already on the followed arc, as in the linked pdf. These drawings fit in better with the systematics of the approach that I use. Do you folks not also try to first receive a near-south satellite?)

How does 5G interference manifest on C-band? We have locked quite a few feeds on 101, but they all have complete periodic drop-out's. We'll go from 15.0 dB C/N to 0 then back.

Or does this seem more like a reception issue?
