[QUOTE="Vipersan, post: 757246, member: 325666"] Hi Nano ... If your LNB is as bad gain wise as you say ..I can totally sympathise ...but looking at the photo it looks physically correct. Not entirely sure what you mean by ..it being to big for the bracket ? If you mean the fitted ku bracker on your current dish ...then this will apply to _all_ cband lnbs .. They are all approx 62mm diameter at the opening/throat...so you need to change the lnb holder for the one supplied with the scalar ring set .. This would be approx correct for mounting the lnb positionally and slope wise .. As to the scalar feed ... Is it the conical blue type ? These usually come equipped with three screws which close around the lnb feed ..and there will be a gap around the lnb feed and in betweed the bore of the conical feed .. This is normal ..as the lnb tube/feed slopes... being wider at the front and narrowing in diameter toward the actual electronics.. Again ..this is normal ...and the conical feed bolts are adjusted to grip the feed and accomodate this ..as its position varies according to the fd / type of dish its fitted to. Some pictures of the problems you are encoutering would help ..as this might throw some light on whats going wrong. ..incidentally ...the ESX421 you have ordered from the states is an excellent high gain product ...but will look and 'feel' much the same as the cheapo Taiwan one .. They are all lightweight units ...and physically much of a muchness.. rgds VS [/QUOTE]
