Low Signal for 119 on Superdish

[bdtech]

Hey Guys, I have installed a few dishes in Eastern Kentucky. The typical install will usually yield 100+ for 119 & 110, and 60-67 for 105. I just came from an install (wide open view), I had 120 signal on 110, 75 on 105 (the most I've ever got), and 50 on 119 . I've replaced the dish (thought maybe the dish or lnb array was bent), same result. Anybody got any ideas?

Thanks all.

The first thing I'd look for is a partial obstruction - but you say there's none.

A 3 LNB Dish is a set of design compromises. That may be part of the issue.

Have you tried nudging the 119 LNBF with hand pressure - just to see what happens?

No I didn't, but, along those same lines...a tech from Dish suggested that although everything says to adjust the skew and then DON'T mess with it. Well...you might want to tweak it a little

Thanks

make sure your mast arm is level, then make sure your skew is correct. skew is very important for 119 on the SD.

Dish told us that the skew had a +- 5 deg. tolorance...that seems like a lot of 'wiggle room' to me.

I thought that the skew did not matter for the LNB? Isn't it the same as the polarity?

 

[bdtech]

No, the skew is the rotation of the dish.

You should NOT move the skew under any circumstances. Make sure the pole/mast is perfectly plumb on all sides. If 105 and 110 is coming in good then 119 should be coming in good as well unless something such as a tree is blocking it partially.

Maybe you're thinking of FSS and C-Band - vertical/horizontal polarity where "skew" is either dialed into the LNB by rotating it, or under control of the receiver controlling it remotely.

DBS uses circular polarization that doesn't need or use that type of skew.

The term as used with D* and E* has to do with the angle needed to get multi-LNB dshes aligned right.
