Standing behind a standard dish 500, I know the signals swing in from the upper-right portion of the dish and then on the LNBs. It helps to know that when the LNB is pointing directly at a tree, but you're all clear on the right-hand side.

Standing behind the new Dish 1000.4, are the signals still swinging in from the right side or from the left?

 

[Jim5506]

Yes from behind the dish the lnb's are (from right to left ) 61.5, 72, 77.

The signal is reflected off the dish (lens) so it is reversed to the lnb's.

All single reflector devices work like this.

On a standard Dish 500, standing behind it, 119 comes in from your right, hits the dish, and crosses over to the left-hand LNB. 110 comes in from your left, hits the dish, and crosses over to the right-hand LNB. The arm on the dish is pointed roughly in the center between the two satellites (around 115 or so).

That may be true in Cali., but on the East coast both 119 and 110 come from the right side of the Dish 500, as jarvantgroup indicated. I don't know about the 1000.4, I have not installed one yet

I would have to check to be sure, but i'm pretty sure IIP is right...if you had a dish 300 pointed at 110, and another pointed at 119, and you stuck a 500 pointing for both, it would pretty much be splitting the difference between the two....the signals come in from either side, not both from the right.

What's a 1000.4?

What's a 1000.4?

New dish for the Eastern Arc.

 

[Raymie]

Ah. I don't know if BobaBird has a 1000.4 page yet on the EKB.

If you in the Western states, say Nevada, your analogy would be dead on. But if you did that here in the East, the LNB arm would be roughly point at 101... to the left of both sats.

Which doesn't help when you do an install for a know-it-all customer who insists that Direct and Dish are the same company and use the same sats.

Details on the Dish 1000.4 are at http://www.dishuser.org/easternarc.php . All the early info referred to it as the Eastern Arc dish before Dish started calling it a 1000.4. I'll check later to make sure there's a link from http://www.dishuser.org/Dish1000.php .

Thanks for the responses. But I'm still assuming that if standing behind the dish (On the East Coast) 119 beams in farthest from the right hand side of the dish, and then 110 will beam in 9 degrees to the left of 119. So is it safe to assume since the 1000.4 swings towards the Eastern Arc, that standing behind the dish, 77W beams in farthest from the right hand side of the dish, then 72.7W 5+/- degrees to the left and then 61.5? Or coming from the Eastern Arc, will those figures be reversed, maybe beaming in from the left hand side of the dish? From my area, the skew on a Dish 500 is 128. On a 1000.4 it is 79. So I assume since it is skewed on the lower side of the 90 degree tilt, maybe everything is beaming from the left hand side of the dish. It all new to everyone, so any input, especially input from the field would be appreciated.

just for our birdog posse:

posted 8/25/2008 - Files for the new DishNetWork Eastern Arc satellites at 72.7 and 77 are not yet available.
ETA for the 72.7 file is by August 30, 2008. ETA for 77 file is by September 5, 2008.
NOTE - the Dishnetwork 61.5 file will also lock when dish is pointed to 72.7

in kissimmee, fl...

if you point a dish 300 at 119 - azimuth is 241
if you point a dish 300 at 110 - azimuth is 232

both are pointing directly at the satellite

if you point a dish 500 at both - azimuth is 236

pointing in between the two signals....one from each side.

 

[Jim5506]

Some of you guys are talking two different languages.

In the east a Dish 1000, 1000.2, etc. will always have the signal coming from the west toward it.

Around Arizona the dish will be pointed almost due south and signals come from slightly east (110) and slightly west (129).

When the dish is rotated around to receive the signal (viewing from behind the dish looking at the lnb) the 129 signal will ALWAYS come in from the right and hit the left lnb and 110 will ALWAYS come in from the left and hit the right lnb.

If it does not you get no signal, it misses your lnb.

 

[puckwithahalo]

that's what i'm trying to say

 

[RickDee]

Yes from behind the dish the lnb's are (from right to left ) 61.5, 72, 77.

The signal is reflected off the dish (lens) so it is reversed to the lnb's.

All single reflector devices work like this.

I think you may have your LNBs reversed. From behind the dish, looking up in the sky toward the satellites, the LNBs are 72.7°, 77°, and 61.5°. The satellites would be at 61.5°, 77°, and 72.7°.

That would be correct if the skew was set to 90 degrees, but in Kissimmee the skew is 135. (I had to look that up)

The LNB arm would be pointed at azimuth 220 (give or take). There's no way the signals can "crossover" so that each one comes from each side of the dish. In this case both 110 and 119 come from the right side.

We ended up the new 1000.4 yesterday. We just cannot get 129 so the installer and his supervisor installed the 1000.4. He said they just came out and it was his first. I'm now on 72.7 and 61.5. From what they said 77 was up but not active (?). We've got everything we had on 110 & 119 and now more and all is fine.

You are 100% incorrect. If you bothered to look up the skew for Kissimmee, why on earth didn't you look at the Az value while you were there and find it is the 236 value posted, not the 220 value you made up in your head. The Skew has nothing at all to do with the Az of the arm.

EVERYWHERE in the county, the arm of a 500 points between the Az value for a 300 at 110º and the Az value for a 300 at 119º. Pick your zip code or any other zip code you want, enter it into a receiver, select a 300 dish and write down the Az value for 110 and the Az value for 119. Add them together and divide by two. Compare that value to the Az shown for a 500 and you will see the arm points directly between the two sats. The Elevation for the 500 is also the average of the two El values for pointing a 300 at 110 and 119.

Put 34741 into a receiver and select a 500. It says the Az it 236, between 110 and 119 Az values using a single sat dish. The arm does NOT point to the side of both birds, it aims between them. EVERYWHERE. Skew has nothing at all to do with it.
