HI,
We are connecting two buildings about 200 feet apart. We will be using 2.4 Ghz. Does anyone have any suggestions about the type of antennas to use? Low cost is important, but not if the solution does not work well.
Thanks,
Jerry

I just installed a pair of these flat panel patch antennas in a similar environment (100 ft apart for ours)which I am very happy with:
At 200ft, almost any type of directional antenna will work. This sounds like a commercial adventure, so I won't recommend any do it thyself antennas. If you are impoverished, methinks an 8dBi panel (patch) antenna is sufficient. I like Maxrad 9 ($25), 13 ($35), or
18dBi ($60) antennas because of the ease of mounting (swivel ball with a hose clamp to a vertical pipe). If you're into 802.11g type performance, your main concern will be to insure that you have a very strong signal, with little interference from other co-channel users located to the sides of the antenna pattern. If this is a tall building, that has the potential to see other co-channel users, I would make some effort to block the signal from other directions with something absorbant (not reflective). Therefore, I would NOT suggest you use an omni or yagi, but instead use a panel (patch) or dish antenna. I can run a fade margin calculation to determine the minimum required gain, but I need to know what you're working with, how long the coax run, type of coax, expected speed, etc.
I can't resist.
Build your own biquad panel:
Or, build your own panel (patch) antenna:
