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.

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,
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.
Glad you got it sorted out and going good.
