How can I get better range out of my long distance Wi-Fi antenna?

Episode 936 (21:31)

Bob from Manhattan Beach, CA

Bob has a Rogue Wave Wi-Fi Bridge which allows him extend the range of his wifi signal up to five miles. Leo believes the bench mark is ambitious, although over water it'll travel further than on land.

The problem here is that while Bob may be boosting his ability to receive a signal, the Wi-Fi router he's trying to access isn't being boosted at all. So at best, he'd be receiving a very low powered signal.
