Cross-Sat Yagi 144/430 MHz 4+7 el. 100cm

For armateur satellites use - 146 and 437 MHz.
After the idea of DK7ZB

The antenna is designed mainly for communication through amateur satellites, provides a very good reception and transmission quality. At the same boom are situated two antennas. First the 144 MHz band and the second at 430 MHz band in opposite polarity.

These antennas are powered by separate cables.

Using two antennas and splitters with appropriate phase shift can be obtained circular polarization in both bands for superior communications satellites during the entire flight.
