18" motorized dish

[keegster17]

guys having a small issue with a 18" dish with a hh90 motor. trying to accomplish hitting 91,110, and 119 only. my problem is the back of the dish rubs on the corner casing of the motor housing slightly. I added some thick washers but it is not enough to clear. any suggestions on how to resolve this?

Just a thought but you could try a cheap cutting board. Worked for me when I was screwing around with superdish. I got this one at Walmart for about 4 bucks. 8 1/2 x 11 about 1/4" thick. Wasn't pretty or scientific but it worked. Or find one a little thicker and just cut it to fit with a jig.

On second thought this may not work. I've got sg2100 on the brain. Using a sg2100 with my 18" dish. :rolleyes:

looks like the sg2100 allows more clearance from the housing and the back of the dish. would a dish 500 be better than a direct tv dish (18") that I am setting up now.

Not sure if you would still have enough clearance for your motor. The pic of the superdish had a skewplate off of a dish 500 attached to it. One other problem with the dish 500 is the lnb arm. It is shorter than a standard dtv dish arm. So in order to use a single inb with the dish 500 you would need to extend the arm out. I've done it with a piece of 1x2 attached to the arm to give it some length for fta birds. But elevation will play a part in there as well. The higher the elevation the more problems you may have with clearance.

Can you post some photos?

We might be able to ID your problem with them.

Here is an example of my above post. A little project I'm working on. Added a length of 1x2 to a dish500 skew plate to extend the arm out. My elevation is 24° and even then I had to make a spacer to go in between the motor arm and plate for some extra clearance. Sorry about the pic quality. My hands shake a bit.

guys i am still working on this setup. i have a question, i can lock down on 110 and 119 no problem however, when the motor turns to 91 it seems the dish needs to tilt higher to hit it. i am using a old DTV 18" dish. my long. and lat. are 79.5 w and 43.5 north. I should mention I have a house close to line of site for 91, but it doesn't seem to be the issue, as i will tilt the dish higher by 2 markings or however you describe on the side inclination and declination. i am i think at 28 to get sats 110 and 119, but will just miss 91, if i raise the dish to 30 i hit 91 but miss 119 and 110. i used a little plastic level for the pole seems level, and the motor is set to 43.0. I am wondering if the housing is the issue, or is the dish not big enough? i think the dish size is fine as I can hit all sats? I will try to show some pics later. the dish is still rubbing on the motor haven't solved that issue yet, which also creates a problem to tilt the dish back more too.

I would use a different dish, say a 30", this would give you the required clearance for the mount to motor.

The DTV dish may have an offset, this will cause the dish to not look right when pointing to the satellites on ether side of center.

A dish that is designed for a single LNB would be the best choice.

abouttosnap when you mentioned a cutting board you were referring to the spacing so the dish would not hit the motor? Did you have a an issue like this with the SG2100 motor? or did you have lots of clearance?

Is the arm of the motor pointing down?

[keegster17]

glatt not sure what your asking?

Had to figure out a way to attach the skew plate off a dish500 to my superdish. Skew plate off a superdish fits a 2" mast poll. I needed one smaller for the motor arm. So I attached the cutting board to the back of the superdish and the skew plate off a dish500 to it. Nope wasn't a clearance issue.

If the dish is keeping you from getting the correct elevation then that maybe the problem. One thing I've learned with a motor. Three things have to be set correctly or as close as possible. The motor elevation, dish elevation and the motor zeroed out per your longitude. Or zeroed out to the closes satellite to your longitude. No matter how you mod the dish afterwards if those three things are not with in close range the motor will never track the arc.

After looking at some of the different mounts for different dishes, I can see one way to do this, you can remove the bolts that hold the pan to the mount and use longer bolts, this will the addition of enough washers you can then space the pan out further from the mount.

This may give you the required clearance to miss the motor.

Be sure to use the same amount of spacers/washers on all bolts.

Try a larger dish, worked for me.

Terryl, good suggestion, actually a friend advised the same thing, so I did this the other night it did help, I used four stainless steel carriage bolts and 2 over sized14328143291433014331 nuts to act as spacer. looks great. however didn't help me, my true issue I believe is the house, I can not get 91, i have to raise the inclination to notches on the dish to receive 91, which then puts me out on 110 and 119. I think I may be stuck having two dishes in two separate places to get 91, 110 and 119.

[keegster17]

i added some pics, here are shots of the direction 91 should be, it is not exact, but if oyu follow the LNB it is the direction, does this appear to be enough room to receive 91 or going by the pics, that the house or possibly this tree are in the way?
