|If you can get the antenna outside the building, up on the roof, than you won't have any interferance from the building, and line of sight is the ideal situation. However, you will pay dearly for every foot of coaxial cable, particularly if you use garbage cable. I only use coax if I have to, and when I do, I only use low loss LMR400. There are workarounds for your situation, though. You should consider an equiptment upgrade, what I would recomend would be a high power outdoor POE router, with DD-WRT preferably, so you have the option to use it as a bridge or a repeater. Ubiquiti Networks specializes in this sort of stuff, and at the most affordable prices. This is WISP as opposed to SOHO, but at a SOHO price. As a bridge, the router serves as a client, becoming a wireless "patch" for your wired lan, either your computer's earthnet port, or another router's wan port. With my Ubiquity Bullet2HP for example, the idea is to attach the router directly to the antenna, outside, so there is NO coaxial cable at all, so no loss. Data streams through the earthnet cable, as does the d/c power supply. so that it needs only the earthnet wire to connect it. The Bullet2HP stands for "high power", @ 800mw, with an Atheros WIOSK chipset, it gets amazing performance, anyway. You connect that either to your pc, or another router (inside the building), this is then a repeater. But DD-WRT has a repeater mode, where it will connect wirelessly to another wireless AP as it's WAN, while also broadcasting an SSID and serving as a wireless AP at the same time. The advantage to using a seperate router as the AP is that you can set that up inside the building, but you would only need to consider that if you have trouble connecting to the router on the roof. Check out Streakwave wireless for the best deals on Ubiquiti equiptment. Also, my all time best wireless card ever (am into the wireless, I build antennas, and collect long distance "QSL's" to public hotspots, I used to be into HAM radio, so I have used all sorts of wireless cards) is also from Ubiquiti, the Wifistation EXT (external antenna) client card. It has the FCC's legal limit of 1000mw, has a 10' usb cable, and is weatherproofed, so it can be outside connected directly to the antenna, with no coax. It gets about 50 AP's right now, from inside my house, which is a one story, and that is with the stock antenna that it came with. These are $30 at Streakwave, and I can assure you, there is nothing better, no matter what you spend on it. You can get away with the 10' usb cable and one 10' active repeater usb extention cable, in fact, I have used mine with 2 of them, for 30' of usb cable. If you can get that close to the antenna, that will do for you. But the POE can go through100' of earthnet cable, no problems.|
