Dual LNB replacement query

Hi There,
Anyone know if the below dual LNB will work for a standard 60" dish and standard FTA satellite receiver. Receiver is about four years old and looks like something that would have been purchased in Lidl. Don't know h

Thanks a million

I assume you mean a round 60cm dish? Not a SKY perforated metal dish (which is slightly oval)?
Assuming it's a non-SKY dish it should have a 40mm collar which will take a standard universal LNB. If you're replacing, you might consider getting a quad LNB which will give you the opportunity to add extra receivers.
If it's a SKY dish, you need a specific LNB type to suit the dish focus and LNB arm fitting.

Get a Quad.

Yip, It's a non sky dish but it is perforated. Do you think it will still work?

Thanks again
Brian

Unusual to see a perforated non-SKY dish. Is it like this?

If you're sure it's not a SKY dish, then a standard LNB will fit in the 40mm collar. SKY dishes use a proprietary spigot on the LNB which clips into the arm on the dish, although the design has been modified in the past year or so.
In any case, perforated metal dishes tend to rust quicker. Get a quad LNB to give you more scope with adding extra receivers or if you're going for a PVR at a later stage.

To avoid confusion, I would add that the Amazon LNB is a "twin-output" type not a "dual LNB".
See definitions: http://www.satcure.com/tech/lnb.htm#twin
The Amazon specification doesn't state what shape dish it's designed for and it's impossible to guess. See http://www.satcure.com/tech/lnb.htm#oval

The eBay dish is a perforated (not "mesh") dish and, despite the claims, it is NOT "wind resistant". Perforated dishes actually present slightly more wind resistance than smooth dishes and bend more easily.

Yes. Perforated dishes are cheap to ship and make. Rubbish quality as it's harder to seal against moisture & air, rusts easily.

As Liameter says, they may even have higher wind loading at certain angles to wind.

A quad is MUCH better value and many Multiswitches can use at least one Quad rather than Quattro.
