I just don't get the issue people have about "wi-fi theft" these days. All one has to do is use WPA encryption, use a long random password, and keep the password private.
As for antennas, a dandy set of designs is available:
Long Range Wi-Fi
Parabolic antennas using hacked satellite TV dishes, yagis, and an easy spiral on pvc tubing. Good for miles and miles.
Telephone service is another matter - who wants to hack an iphone to use an external antenna?
