He's trying to sell you a $43 (list) AntennaCraft model 5884 that you can currently buy from Radio Shack on sale for $34. It isn't even a knockoff, he's just reselling it for a higher price than you can buy it for in a retail store, plus you get to pay for shipping on top of that. The AC 5884 is one of Antennacraft's lightest weight, "economy" antennas and you can bet that large birds or ice storms will make short work of it if installed outdoors.
