LNb for sly dish

[cjb1971]

In the future i will be upgrading to a 1m motorised dish but in the mean time would replacing the lnb on sky dish improve my picture quality-some channels are a bit choppy,and then use this upgraded lnb when i change my dish.

Whats the best quad lnb out there as there seems to be quite a few all around the £40 mark

Re: LNb for sly dish

If you have signal or quality problems just consider upgrading the dish diameter to a higher one, i don't think you'll see any improvement by changing the LNB

If you have a mini-dish then they are pretty standard in order to fit the dish. I got mine for only £7 and it does the job as well as my 1m dish with 0.2 LNB.

If your dish is aligned correctly you shouldn't really need to spend lots on an LNB? I'd check your alignment first :-)

Re: LNb for sly dish

The inverto is a good lnb....another make is the 'Best' 0.1db of german design. One thing though there is nothing like having a bigger Dish to make up for those weaker signals although to be quite honest with you the 'Best 0.1 seems perfectly tailored for the Sky U.K. because it brings in those signals 'loud and clear'.
