So I've been looking into doing the primestar dish mod with a diy biquad design, but after looking at dish specs for both primestar and directv they both seem to be designed for frequencies below 2.4ghz. I only have a directv dish to work with and was wondering if anyone could give me some input. I can't find anything on google comparing the directv dish to the primestar dish.

Should I ditch the directv dish and search around for a primestar?

Since the dish isn't made for 2.4ghz is there a major difference on what could be acheived with a dish that is? (be it custom made or readily availiable) Why does it work so well if it's not meant for the 2.4ghz band?

Have any of you guys messed with them? How far did you personally manage to get a decent point to point connection?

As of yet I do not currently have a use for it. I am only making it (or 2 of them) for educational purposes. Perhaps in the future I could pass on the signal from 10 story building to elsewhere as a charity for the local free wireless dudes.
