    Greetings!

    Reading the posts I noticed complaints of signal loss during Sky HD transmissions during heavy rain, storms etc.

    I am in the process of upgrading from standard digibox with mini-dish (no problems whatever the weather) to a Sky HD install and wondered if any advantage is gained by installing a larger dish at this, first, stage?

    I do have a larger dish with quattro LNB feeding a multi-switch. As you would expect, the signal is more robust and does not tend to drop out in heavy rain.

    As above a larger dish certainly helps.
    Ive got a triax 64 cm dish the signal strength is 80% with quality at 100%.
    I get very little drop out while its raining. but if a storm cloud is in the wrong place it still kills the lot dead .

    Thanks for responses,

    Tim, you said you used a switch, do you mean that you have an LNB aligned to another location ?

    I have read elsewhere that it possible to pull in other sats, even with a fixed dish, has anyone else done this and any observations about quality ?

    It depends on where you live. If currently you live in the South of the country and get a good signal in all but extreme conditions you should not need a larger dish as the picture once stable will not be "better" with higher signal level. If you live in the North or Scotland it could be worthwhile.

    The boxes are designed to handle the signal level produced by the standard dish and lnb set up so using too large a dish (or a more sensitive lnb) can result in overloading the receiver and the need to fit attenuators.

    I will leave the present dish, where it is for the moment,
    someone can always shin up later.
    Thanks all.:thumbsup:
