The Invacoms are heavy, I had a SNH-031 but didn't see it was any better than any of the others. Honestly, this Skymexico lnbf is really good, I ordered the Extreme II and the skymexico and the little, light, skymexico delivers more signal. I might add, I have a GeoSatPro dish and you need to have the lnbf all the way back to get in the right focal distance, the extreme, because of the way it is built made it so I couldn't get it back very far so that might be the reason for less signal. Anyway, for $6.99 you can't go wrong. I'm going to buy some more for playing around with. Not sure if they are DMSI, the one I got is unbranded, not a thing on it. The box has some Spanish on it....I think its Spanish. I noticed some DMSI branded standard lnbf's on that site that look identical to the Skymexico, I think I might check out one of those too. They are small, don't catch much wind and are light. Wish I could find a circular one that size.
