Default Connecting Hi gain antenna to router

I have wireless internet in my office which is a small building on my yard. A Belkin N router sits on window sill in my office and besides sending signal to the computers there sends it to my house which is about 150 feet away. The signal there is spotty at best. I was thinking of connecting a hi gain antenna to the router, but I am having trouble coming up with a connection. Most of these antennas use an N connection but the only thing to connect to on the router would be an ethernet type connection. Is there an adapter for this, or am I heading down the totally wrong path?

I used to have same setup except the ISP signal was coming from the house's router to a WET54G bridge in my office. There it plugged into an 8-port switch and I had cat5e patch cables running to the computers in the office. Same problem but implemented in reverse. The house's router was the problem... a very small, non-replaceable antenna on it (btw, my WET54g, v2, is up for sale, $30 + shipping).

What you need is a router that has a replaceable external antenna. Usually it's an RP-SMA connector.

The best buy I found recently was on this $30 Netgear at newegg.com: HERE. I've got one coming Tuesday (10 Nov 09).

Here's the best omni antenna that'll screw right onto it: HERE.

If you've got a spotty connection today but it will connect sometimes the above combo should get you a good connection and total outlay s/b <$50. Plus maybe you can sell the old router on Craig's list or something.

For even more signal go with an outdoor directional sector antenna like: THIS. This one is a 180 degree pattern so aiming to the house will be no problem. It uses a RP-SMA also so you'll need a male RP-SMA to male RP-SMA cable for it. Keep the cable as short as you possibly can because that cable will drop about 1.3dbi per meter. So you get +10dbi out of the antenna but drop -3.9dbi of that with a 3m cable. Whereas the loss w/ drop to -2.6dbi with a 2m cable. Overall still a HUGE gain over what you have today.

If you really wanna be king of the neighborhood APs then you need to start looking at outdoor radios like the Nanostation. They start at $50 w/o the pole you need to mount it to and go to about $150. The 100w version which is probably about double the power of your belkin and has a 60 degree, 8dbi gain antenna built right into it. You should be able to start pegging some meters in the house IF it's line of sight clear to the house (no buildings, trees, etc).. a strong, narrow beam flashlight is good for confirming this at night... as long as the neighbors don't call the cops on ya ;-)

Good luck, Da Shu

PS: Just noticed u r using "n". Good if you are steaming video or high bandwith stuff to the house off of a computer in the office... otherwise for Internet content, etc, you'd probably be better off with b/g equipment.

Exclamation Actually a better

screw in RP-SMA antenna (rubber duckie) is probably THIS one.

Plus these guys actually answer emails with HELPFUL info and they only sell top tier gear. Plus, it's a buck cheaper.

CORRECTION: I gave you the loss on the cable per FOOT... per meter it's about -1.3dbi (.39 per foot). Fixed original reply.
