Dish Network amplifier

[rsers5]

I have a cable run of about 375' between a Dish Pro Plus (Dish 1000.2) and the receiver. 350' of this run in RG-11. The remainder is RG-6. I am having trouble with the picture freezing. Is there an amplifier I can use to boost the signal from the dish to the receiver? Thanks!

I would check my fittings first....especially the notoriously hinky RG11s.
