KE-137 QFH Antenna NOAA, ACARS 135/137 MHz

Circular polarised antenna for reception of NOAA weather satellites on 137 MHz, or ACARS transmissions on 135 MHz. The KE-137 is a quadrifilar helicoidal (QFH) antenna. Due to the construction of the antenna the satellites are picked up at a very low angle above the horizon, but equally well when right over the antenna.

The circular polarisation is required to compensate fluctations of the signal strength. And the same applies to aircraft and their ACARS transmissions on 135 MHz, which can be received with the same antenna. The antenna is weatherproof and intended for installation on a mast. Clamps for mast diameters from 25 to 65mm are included. Height c. 100cm, weight c. 1100g, connector PL female.
