LEO Pack 2 meter and 70 cm CROSS Yagi  For Ham Radio Satellites LEO

LEO satellites – Low Earth orbit satellites in Ham Radio.

LEO satellites have a circular (or elliptical) orbit at a height of 250–2000 km from the Earth surface. The maximum time during which a satellite is above the local horizon for an observer on the Earth is up to 20 min. This time is used to transfer data, images, and photographs to selected ground stations positioned in strategic locations.

A number of low earth orbit (LEO) OSCAR satellites use frequency modulation (FM). These are also commonly referred to as “FM LEOs” or the “FM Birds”. Such satellites act as FM amateur radio repeaters that can be communicated through using commonly available amateur radio equipment.

Ham Radio antennas used are:
1. PA144-CROSS-8-1.7A – 2 meter cross antenna with 4 + 4 elements on 1.7 meter boom.
2. PA432-CROSS-16-1.7A – 70 cm cross antenna with 8 + 8 elements on 1.7 meter boom.
3. 144 – 146 MHz RHCP Kit used to connect two connectors on 2 meter cross antenna and make right-handed circular polarization (RHCP) which is best for satellite communication.
4. 430 – 440 MHz RHCP Kit used to two connectors on 70 cm cross antenna and make right-handed circular polarization (RHCP) which is best for satellite communication.
5. Brackets for antennas, Baluns and Connectors are all included in LEO PACK.

Optional: 40 mm aluminum pipe is possible by order.
