"Ship to shore and shore to ship using satellites, and air to ground, and space to ground, can be by relatively low power directional beams, but ground to air and ground to spacecraft will still have to be broadcast."
You can work a low orbit satellite from the ground with a decent antenna on a handheld 5 watt transmitter using UHF. The trick is finding a vehicle that you can use to help. A small handheld yagi should also do.
