A 430 MHz ( 70 cm ) UHF preamplifier with innovative design. Input notch filter for LTE frequency. Noise figure of 0,3db. Perfect for use satellite, EME, contest and dx. Anticorodal Aluminium cylindrical Design.
Waterproof pole preamplifier designed for the reception of APT satellites with NOAA and METEOR VHF in the frequency range from 137 to 138MHz. The preamplifier is equipped with a high Q input band pass filter followed by a new generation low noise amplifier stage. The gain of the preamplifier is 20dB and there is a by-pass relay to exclude the preamplifier. It can be powered via a coaxial cable (a bias tee is required) or externally via an SO239 connector. It is protected from electrostatic discharges, polarity inversions and from disturbances in the power supply. The pre-amplifier can also be powered by classic 5V USB sticks via the coaxial cable.
Hybrid filter passes band / passes high designed and made to allow the perfect signal cleaning on the frequencies of the Ministry of Defence such as the Forces of the Order and / or Vigilance of Fire from 76 to 79MHz. It allows the elimination, with over 60 dB of attenuation, of the signals present on the 88-108MHz broadcasting frequencies while maintaining a low insertion loss from 76 to 79MHz.
Low-figure preamplifier with a SAW filter in input. New version with bias tee and external power supply. Power supply voltage from 4.75V to 16V. Ideal for the reception of radioprobes, satellite communications or metererological systems from 400 to 407MHz. Antique aluminum container. PL connectors.N on request.
