I will only add that the first thing that someone should do when running any type of wireless link would be to change the password or access code. Many people leave the password at the factory default, making it VERY easy for others to hack into your system. I know this for a fact as i have customers that have purchased high gain directional antennas for this very purpose. Sitting in my shop and using one of their antennas and laptops, I've seen a customer log into a nearby business that is over a mile away with consistent results. This is with the antenna INSIDE my shop, which is loaded with tons of metal and typically provides horrible reception for most cell phones and high frequency receivers. As such, a hacker with such an antenna mounted outside of their house or on their vehicle could literally pick up a strong signal for multiple miles. Some of these folks literally drive around in their cars looking for open wi-fi's, logging the addresses and hacking into the systems. This is called "war driving" amongst computer geeks.
Needless to say, once someone found that entrance into your computer network, they could do anything that they wanted to if they were skilled at hacking. Given the fact that only a "skilled hacker" would be going this far to get into someone's computer, you better do what you can to maintain security. I can tell you a few stories ( funny to listen to, horrible if you were the recipient ) of jokes they've played on people with passwords in the default position. This is not to mention the illegal activities that they could do ( if they wanted to ) using your computer as the source. BE CAREFUL !!! Sean

PS... One would think that these would be big antennas, but due to the very high frequency that they operate on, the antennas are quite small. A 13 element yagi with tremendous gain is less than two foot long and fits into a small diameter section of PVC tubing. As such, they don't even look like an antenna in the least.
