would this really help rain fade significantly? i want to use it for directv. it rains so much here in FL that it's driving me crazy. bigger the better? or waste of money
100CM dish

it should make a big difference keebs bigger is better when talking about satellite signal but nothing will help in a downpour.

what model of direct tv dish are you replacing?
Single or multi head lnbf?

Reason I ask is the elliptical dishes they're using these days is optomized for 3ish sats. And they are getting quite large.

The big dish pictured is for a single sat (driven with a motor).
Sure you can put a multi head on it - it'll probably be just fine.
It should help with some rain fade.
But I think there are diminishing returns. The off axis LNBFs might be only as good as regular elliptical dish from vendor.

If you do go down this road please do post back your results.

I do get better performance of Ku with my 4 foot dish over 30" dish - especially during rain fade. I still lose the picture during really heavy storms but it seems to hang in there and come back faster than before.

If you are using a small 18" with a single lnb one or our 90-cm dishes with an Invacom Quad or DSL2 would greatly improve your signal
