    "content": "Hello Luc,\n\nLike any other fleamarket/hamfest/ebay item, you do not know what you have\ntill you get it home and and evaluated on the test bench. Bid \naccordingly.....\n\nThe feed is probably a simple dipole. Take the plastic housing apart and\ntune the dipole (shorten/lengthen) to where you want it.\n\nOr, get another feed for the freqs needed.\nThe manufacturer may offer different freq response feeds for their same \ndish.\n\nMy first gridded dish I tuned up for 2304 MHz and it performed well \nafterwards.\nThe gridded dish on the satellite tower came with a decent VSWR at 2400 MHz.\n\nThe fades in reception of 2.4 GHz satellites are due to using a linear \npolarization\nand NOT a circular polarization. Try a circularly polarized feed.\nOr try a H AND a V linearly polarized antenna system,\nselect in the shack which one to listen to.\n\nStan,W1LE   Cape Cod    FN41sr\n\n\n\nLuc Leblanc wrote:\n> For those who are using WiFi 802,G beam on S band \n>\n> 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) \n> Even if at theses frequencies things are a bit larger i'm guessing the 16db gain figures are surely not standing at 2.4ghz.
