I saw this setup and think it is brilliant the way it is mounted, as the antenna goes up and down with the TV antenna. Also if you are a little tech savvy, the router he bought for $150 is just an old Linksys WRT54G with a special firmware called DDWRT. If you google "DDWRT universal wireless repeater" it will give you instructions on how to configure a router just like the one in that blog. When configured, you plug it in and it starts looking for open WIFI and connects to it automatically, than it connects your wifi network thru it.
I already have the router configured, I just need to buy the antenna and I have to figure out how to get the cable thru... maybe thru the Fridge vent???
