    I check this site very often to get info, its amazing the knowledge here. I was just wondering about the wide angles needed for the slimline dish for hd. Correct me if I am wrong, but is 20 degrees needed on both sides to get a good signal? I get probably half the hd channels I should be getting, because of trees I am told. If it takes that much clear area, there should be a lot of people with this same problem. I don't see a lot of this talked about though. Maybe I have some other problem? I've never had any problems until the hd channels were launched. If a person needs multiple dishes, or something like that, I would think that would be a hard sell for switching to satellite. Thanks.

    Most of the channels HD channels are now located on either 99 or 103 degree locations. The main dish location is 101 degrees so that spread is not that far. The other satellite locations serve mainly SD and are 110 and 119 degrees so the full spread is 20 degrees in the sky.

    In my case I can see the entire southern sky and I'm on the north side of a hill. The sats are pretty high in the sky for most people ..

    20 degrees is correct, but not on each side.
    I have lots of trees, in fact on google maps all you can see are the trees at my house.
    You need about 2.5 degrees on either side of the 101 SAT [for 99 & 103] and then "just" slots for the 110 & 119 SATs. With my location there are trees between 103 - 110 - 119.

    20 degrees, absolute minimum, so say 25 degrees. Check this out: dishpointer.com. Just enter your address, scroll down and select the DirecTV 5 LNB dish (centered on the 101's). Also select the 119 satellite for your farthest west clearance.

    I'm thinking it may not necessarily be tree interference, but it's possible. Take a look (and display here if you can) at the signal levels, in particular the 99 and 103. Might just be an alignment issue. Also look at the actual "meter" (bar graph) levels and see if they are fluctuating. If it truly is tree interference, you will (should) see quite a bit of variance. Happy hunting.

    See the links in my signature below. This week is the ideal week to use the Sun's position in the sky to help you "see" where the satellites are located and verify line-of-sight. The other link provides information on using multiple dishes if you need to get around trees or buildings.

    and some of us dont have many tall trees around (me) :p

    My dish has a view of the whole sky 360 degrees from the top of my roof!

    But I know what a PITA trees and such can be for some locations, sometimes some trimming can open up the spots you need to get a signal, the whole 20 degrees does not need to be clear.

    Thanks for the info people. I am still confused. Signals are in the 80's to 90's on 101,110, and 119. Sat. 99, and 103 show 0%, but I get my locals in hd, and a few of the new ones, which I though were on 99 and 103. Thanks for all your help.

    Sounds like you just need to have your dish fine tuned.

    Did they swap out your dish? The HD dishes need to have 5 LNBs, but the 101-LNB may be a "fat" one that actually has three LNBs inside the feed horn. If you have an older dish, it only has 3 LNBs for 101, 110 and 119.

    What model of receiver do you have?

    Please post all your tp signal strengths in grid format from the 103(c) satellite menu setup page under Satellite & Antenna > View Signal Strength. Sounds like your dish needs re-alignment.

    I don't see a 103(c), but this is what 103(a) and 103(b) show.
    (a) 1-8: 0,0,0,0,0,0, n/a, n/a
    9-16: n/a,n/a,n/a,n/a,n/a,n/a,67,0
    17-24:66,75,0,0,0,0,25,23
    (b) 1-8:0,0,0,0,16,0,41,0
    9-16: 41,0,35,0,34,0,n/a,n/a

    Your dish needs re-alignment. Are you up for doing it yourself or are you covered by the Protection Plan? Otherwise there's a $75 charge unless this dish was installed prior to the advent of HD locals in your area, or if no HD locals, the advent of the new national HD channels from DirecTV10, in which case you should be able to talk them into a free re-alignment.

    Your 103 (a), tp 18 will probably go to 95+, and your 103(b)'s should be mostly all in the 90's.

    hey guys, remember by the end of 2008 the LOS should be about 4 degrees as 110 and 119 will be removed.

    How are you coming to this conclusion? What is your source? They are not removing 110 and 119 at this time. Please do not provide undocumented information.

    I believe I remember hearing that at the investor conference. I may be wrong.

    That's very misleading. While programming will be reassigned, that doesn't mean that the space on 110 and 119 is going to go unused. Many people will still need the signals there.

    time will tell for sure. for now the issue of 110 and 119 should be tabled

    110W and 119W aren't going anywhere for at least a few years until they can replace ALL of the existing receivers with MPEG4 capable models. That replacement will not begin in earnest for at least a year according to the recent financial conference call.
