    The UC-4364-531 is a Quadrifilar Helix Antenna (8 cm/3" OD x 23 cm/9" H) designed to operate through Amateur Radio satellites, without requiring an antenna rotator. The goal of this product is to offer Amateurs with space or community restrictions the ability to receive 70 cm HamSat signals, and communicate through orbiting repeaters (transponders). Ham satellites operate cross-band: you will generally need a VHF uplink transmit antenna for 2-way communications. A companion VHF unit is available UC-1464-531.
