Antenna for NOAA and ACARS weather satellite reception DIAMOND KE 137 QFH

Antenna for reception of NOAA and ACARS weather satellites DIAMOND KE 137 QFH  on 137 MHz or ACARS transmissions on 135 MHz. The KE-137 is a quadrifilar helical antenna (QFH). Thanks to the construction of the antenna, satellites are received at a very low angle on the horizon but also when they are vertical to the antenna. Circular polarization is necessary to compensate for fluctuations in signal strength.
This is also valid for aircraft and their ACARS transmissions on 135 MHz which can be received by the same antenna. The antenna is weatherproof and is designed to be installed on a pole. A clamp for installation on poles from 25 to 65 mm is included. Height approximately 100cm, weight approximately 1100 gr. Female PL connector.
