Product information "Outdoor preamplifier for NOAA and METEOR 137MHZ"
PREAMP POLE NOAA METEOR 137MHZ
The preamplifier pole-pond designed for the reception of the satellites APT with NOAA and METEOR VHF in the range of frequencies from 137 to 138MHz. The preamplifier is equipped with band-pass filter with high Q in the input is followed by a stage of the new generation of amplification at low noise figure. The gain of the preamp is 20dB, and there is a relay by-pass to bypass the preamp. And you can feed it via coaxial cable ( must be a bias tee ) or externally through an RCA connector. It is protected from electrostatic discharge, reverse polarity protection and supply disturbances.
Field of use :
- Preamplifier with band pass filter high Q exclusively designed for the reception of the satellites NOAA and METEOR VHF 137 to 138MHz.
- Thanks to its led status outside it is possible to verify during the installation that the power supply voltage comes without problems
- You will be able to connect your antenna QFH, TURNSTILE or VERTICAL directly to the preamp, and install it under it, thanks to its ABS container pond.
- The support can be installed on pipes with a maximum diameter of 60mm.
Uniqueness :
- Band pass filter high Q input is set at the center band 137.5 MHz
