I have a WRT54G in the middle of my house. Im new to antenna's, but looking for a cheap better antenna to extend range. I found this yagi antenna (Enterasys RoamAbout 14-dBi YAGI Antenna) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5713760463&ssPageName=STRK:MEWN:IT and wondered what an expert thinks about it? It would be hooked up to the WRT54G and set next to it, basically as a better antenna so wireless clients can connect to it and not a p2p to another WRT54G. I might leave it indoor in the middle of the house and might put it outside next to window. How much would the range be boosted either way? It says its a directional antenna (not totally sure on what yagi means yet), but I figure it can be used basically as a 14dBi antenna insted of the like 2dBi (or whatever it is) thats included with the WRT54G. Or do I have that wrong? Thanks!
