# AMATEUR RADIO

## Communication using objects away from the Earth's Surface

## Many amateurs find a technical challenge in bouncing signals to and from the moon, and from passing meteor showers.

## Often radio amateurs will be taken up on the space shuttle, and be making regular and fairly easily achieved contact with amateurs on the ground using both voice and data .

Amateurs throughout the world, have also joined together to launch their own communications satellites which carry repeating equipment that will receive signals from the earth, and re-transmit the same signals back to the earth. High above the earth, the signals from these satellites covers a very wide area of the earth's surface. This requires special antennas, motor orised to track the satellites passage around the globe.

## Books are available which describe the making of many types of antennas for various frequencies and purposes. Many Amateurs find making antennas a facinating pass time coupled with their use of the Radio. An antenna is the most critical part of any amateur radio station, and should be the first thing to be given proper consideration.
