My staff live in a house about 700 meter from my office. I would like to send a wifi signal from the office to their house so they will have internet. I have use YAG antennas in the past to enhance mobile phone signals and that works great. Are these antennas and associated bits available here in Thailand, and if so where, I live in Samui.

Any advice or help appreciated.

Thanks and have a Great Day

There are some shown on Shop4Thai. Also SaimMaster Shop and Bangkok Wireless

700M your looking at a point to point bridge and that will make them part of your local network.
