    my 1st time installing, going from 18" to non SWM 5lnb HD Slimline using TV meter only, after doing setup of sat, max signal is 73 on 101, I blocked lnb with my hand and signal did not go to zero, 99 and 103 zero's even with BBC installed,they want their clip-on TERK ota so I then installed that at the dish, then got 771 error, took TERK off, still getting 771 even after power downs and unplugs , mixture of RG6 and RG59 cable, tomorrow going to run RG6 from dish straight to H21-200, if still 771 maybe bad lnb???

    Hooked up old 18" dish for tonite and picture is OK , so receiver has to be OK

    I'm guessing w/o a meter I can't test lnb ??

    I wired the Terk wrong at 1st, maybe cooked lnb??

    First, you should have signals in high 90's for 101. Signals for 99 and 103 need to be in high 80's or 90's. Anything lower is just future problems.

    Second, is there a multiswitch? If so, it MUST be a Zinwell WB68 (or an SWM8). Older multiswitches won't pass the new signals.

    Third, you can't diplex, so get rid of all diplexers. Straight coax from dish to receivers, or through WB68.

    With max signal of 73 on 101, your dish is way off alignment. On 101 you should see a few signals at or near 100 when the dish is aligned. How many transponders are you seeing on 101? You might be pointed at the wrong satellite.
    And unless the dish is aligned reasonable close to correctly, you will see no signals on 99 and 103.
    Are you "dithering" the dish to find the center of the 101 beam?

    This is unlikely (although possible) to be a cable or LNB issue

    I had 70's on all transponders on 101 no matter how much I turned or tilted the dish, what is bothering me is the dish did not zero when I completely blocked the lnb, like the reciver was stuck, but when I rehooked the 18" up the recvr is working fine, I'm going there now to run a RG6 cable straight to rcvr and try the "repeat sat setup" in menu.

    Carl, there are no mutiswitches, this is 5lnb non swm install, 4 outputs from dish,only 1 recvr in this house, there is RG6 from dish to house, then inside house is RG59. The dish did come with PI 21V power inserter, I don't know why ,again this is non swm dish so its not installed

    went to Dishpointing.com to see 101 orientation for that neighborhood, so I feel confident I'm looking at 101

    That sure sounds like a bad LNB. Moving the dish any amount should change levels, and moving it very far (inches) should drop all transponders to zero.

    You also want RG6 with solid copper center conductor for your coax. RG59 is really not acceptable, as it does not have the current carrying capacity for the Slimline LNB which draws a lot more power than the 18" dish did (from the receiver, you are correct to not use the PI).

    Try the new coax run first, but if that doesn't help then replace the LNB.

    Man, you guys were right. I wasn't on 101 sat. What happened is I zoomed in too much on Dishpointer and was just using the neighbors house as only reference to where to point dish at 101. As I zoomed out the angle changed , so I moved dish accordingly , everything after that went good, all sat's in the 90's.

    The lnb stuck/not zeroing story is embarrising. There are cable splitters, inline connectors, old sat cables all coming in this house at one area. When I brought my new RG6 line into the house, I thought I connected inline to the room receiver using the existing RG59 wiring, but connected to cable jacks instead, so all along yesterday the receiver was still connected to OLD dish, no wonder numbers weren't changing when tweaking the new dish.

    Thanks to all who helped

    Glad you got it sorted out and going good.

    Also worth noting that those clip-on OTA antennas usually use diplexing to integrate the OTA signal into the sat coax. That won't play we'll with the 99 or the 103cb. Leave it unhooked :lol:

    Yes, if you don't have SWM, you can't use diplexing because the frequency bands overlap. If you have SWM and "whole home', ditto - diplexing is out. If you have SWM without whole home, diplexing can be made to work with the right diplexers (only some models will work) but DirecTv does not support diplexing in ANY situation so it's best avoided, unless you know exactly what you are doing.

    I figured that since a BBC was mentioned, they were working with a conventional system :lol:

    Yes, I read that too. I just thought I would post the complete diplexing situation for anyone who was reading the post.
