What can I receive with this? 91,110,119?

I sure would like to be able to hit all 3 with this dish... willit do it?

please see photo..

thanks for the help...

not familiar with this dish.

[skater]

im just guessing.....because it says dish i think 110 and 119

but maybe you can get

82 and 91 with it

Nope wont work, it does not have a wide enough receive beamwidth, 20 degrees is about the max on that dish, your looking at about 28 degrees, the outside LNB's (91/119) would be starved for signal.

[skater]

yes but what is that dish for?

just....110 an 119?

[Terryl]

It says it's an HD dish that means it could be used for 110/119 and 129, but not for 110/119 and 91, too far in-between satellites. 110/119/129 = 19 degrees......91/110/119 = 28 degrees.....That dish at most = 20 degrees.

since there are only two eyes you cant get three birds

Simple bracket change for that problem,(dish 3 LNB bracket) but it's the receive beamwidth that limits the satellites it can view.

Thanks guys,

I did make a mistake, I ment the 129 sat not the 91...

So I can only see 2 sats at once with this unit,? not all three?

read post 7 and 8

You can use that dish and receive 110/119/129. You would need a new bracket and one more lnb. Need a bracket that holds the 3 lnbs lined up at 110/119/129.

From a quick search the lnb looks to be designed for the eastern arc...61.5W & 72.7W. Also looks to be a dish 1000.2 but there is always a chance I could be wrong.

You're correct, it is a 1000.2 for the Dishnets eastern arc.

I've done tests on the small 18 inch dishes and the drop off of signal for circular pol follows the cosine of the angle. Since cosine drops pretty slow for the first 30 degrees or so in either direction from center, I usually find that small dishes can do a 60 degree arc pretty well (30 degree loss is down only by 17%, 45 degree is down by 30%). If you ray-trace the off-angle use of a parabola, you see that the rays from different parts of the dish do NOT reach a single spot as they do for the center focal point--that seems to be large factor in linear pol signals but not very critical for circular (I could post a ray-trace image but you can go on-line and and look up "Coma distortion" for an example) .

BTW, I'm not sure about the following, but I think that the larger the dish, the poorer it does off-axis. Think it might be due to the longer path length allowing more phase-shift in signal coming from different parts of the dish. It is just an observation from trying to hang multiple LNB on larger dish and getting poorer results than I expected--not something I have tried to simulate in 2D or 3D modeling.
