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.
