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??

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:
