sky dish, maplin lnb?

[Psychobiker]

hi, bought a dual lnb from maplin on special offer. Upon fitting, no signal received, even though dish orientation didn't change one iota. Are the reflective points on such dishes a bit iffy?

Check the skew setting on the LNb :

Might be a possibility if your using this or a similar LNb although a mini dish requires a matched LNb really.

Have you bought a Sky twin LNB?

Excuse the malformatted message, on my N95.
No, not a sky one, but many customers have used this same lnb with a sky dish with on major shakes.
I bet i've just upset something, will check when it's NOT rainy and windy .
Will check with the original lnb just in case it's a feedline issue

I'm not sure whether they still make twin LNBs for the Sky minidish, as quads tended to replace them. Of course if it is actually a "Dual" LNB then it wouldn't work, as dual LNBs were one Horizontal and one Vertical Low band output.

Yes, a standard 40mm twin/quad LNb will work on a mini-dish but will not perform as good as a matched mini-dish LNb due to it having internal circular scalar rings.

It's possible you have knocked the dish off slightly or a cable connection problem.

I had an Inverto LNB taped onto my minidish for a while, the difference between it and one designed for a minidish were not significant. Probably the skew is a problem as mentioned already.

BTW, it would have been better to grab a Sky quad off fl ebay for about a tenner.;)

On such high powered satellites such as Astra2/EB, you most probably wouldn't see too much of a difference, agreed

can't trust any bloody connection these days-i'll just solder the two together! Cheers again guys, bet i've just prodded the dish 1" off kilter

What it was was a dodge track on the PCB on the back of the pattress box!
Center conductor solder point had completely snapped off

Yes, it's very common on low grade IEC & F Outlet plates.

Glad your up and running anyway
