I've been putting of a 1.2m purchase for a while now. Sounds like its time to bite the bullet, get one and fix it on 125W. Where did you get your 1.2m Patriot? Do you know how it compares with the 1.2m GeosatPRO?
The reason that I originally got into FTA is because of 125W. We couldn't get PBS with an antenna, so decided to try the FTA route.
I really don't know how the Patriot 1.2 m would compare to the Geosat Pro 1.2 m, it would be interesting to know. Most of what I've read about the Geosat Pro has been favorable.
Both of my Patriots were purchased from Rick's Satellites as I could go pickup the dish and save on the shipping costs.
From what I understand, Patriot is defunct- so new old stock is all to be had (i.e., once they're gone, they're gone). As for the dish setup, the mount on the back of the Patriot dish is quite heavy and extremely sturdy- probably sturdier than the dish itself.
My experience with FTA is going on 5 months now. In that time, I've had my first Patriot 1.2 m parked on 125W and have had very dependable reception for all available PBS on that satellite. The only dropouts have been during very heavy downpours and thunderstorms.
