Hello Luc,
Like any other fleamarket/hamfest/ebay item, you do not know what you have till you get it home and and evaluated on the test bench. Bid accordingly.....
The feed is probably a simple dipole. Take the plastic housing apart and tune the dipole (shorten/lengthen) to where you want it.
Or, get another feed for the freqs needed. The manufacturer may offer different freq response feeds for their same dish.
My first gridded dish I tuned up for 2304 MHz and it performed well afterwards. The gridded dish on the satellite tower came with a decent VSWR at 2400 MHz.
The fades in reception of 2.4 GHz satellites are due to using a linear polarization and NOT a circular polarization. Try a circularly polarized feed. Or try a H AND a V linearly polarized antenna system, select in the shack which one to listen to.

For those who are using WiFi 802,G beam on S band
I just found that my Pacific Wireless WIMAX VA 25 -16 antenna for 2.4GHZ has a bandwidth starting at 2.5ghz to 2.7ghz (www.pacwireless.com) Even if at theses frequencies things are a bit larger i'm guessing the 16db gain figures are surely not standing at 2.4ghz. Did any one have a ball game figures of what remains at 2.4ghz? I have no way to measure SWR at this frequency and this is surely not optimal?
Conclusion don't jump too fast on some hamfest deal as what's good for WiFI is not always so good at 2.4ghz!
P.S. I can use the antenna on 2.4ghz and i got fairly good signal from AO-51 when he's in S mode but i cannot get rid out of the fades. Could be i found why?
