New LNB for spiderbox 9000

It seems that my lnb is not picking up channel 4 HD on 12.607 V 27500 3/4 on 28.2E.

Actually, my LNB does not pick up any vertical transponders after 12.100 on
28.2e but is okay on 19 e upto about 12.300 . So i guess i should get a replacment lnb.

What LNB should i get?

Thanks

I use the same, very good lnb.

Thanks to everyone who has replied with their lnb.

I was just wondering about the twin output lnbs. In particular, since there are two outputs, are they ** truely ** independent? I mean if after some time one output deteriotes or fails, will the output on the other one also be affected?

I've only had one LNB fail ever and this was down to a slight crack in the casing allowing rain to enter.
LNB failure in my experience is very rare.
