Not sure if I can continue on in this discussion. I've a lnb query. My old gigablue box worked on the lnb connection I'm using. Now the zgemma isn't picking up channels. It's direct feed to sky hybrid lnb, model EL02B. Does the zgemma need to power the lnb. There's 4 outputs on the lnb, 2 for sky q, one more is for another tv which I can pick up channel 4 & ITV through old receiver Not sure what the issue is. Maybe disconnect the old receiver, maybe 3 feeds is enough. Don't know. Thanks.
