[another Linda]

One of my sons is stationed in Iraq. Until recently we were able to communicate with him via Skype (wonderful!) Now the army (in its infinite wisdom) has switched from a wired internet connection for the soldiers to wireless. Unfortunately, they live in metal containerized housing units (CHUs) and can't get the wireless signals. They could sit outside, but when they have free time it is usually 130 degrees!

I understand there is some sort of antenna you can buy to pick up the signal from inside. My son decided (without checking with us or his wife!) not to buy one because they are expensive. I want to buy one and send it to him but don't know what to buy.

I went to Best Buy but they don't sell it because they are usually used for illegally picking up signals from neighbors. All his wife knows is that is is an antenna "thingy". I'd ask him ... but he doesn't have an internet connection anymore.

Does anyone know for sure what I should buy? Are they illegal? thanks for any help.
