View of the AM-346 amplifier
Masthead antenna amplifier ALCAD AM-346 R903046 is dedicated for outdoor applications in individual antenna systems and small MATV systems distributing the signal to tens of outlets. It is mainly designed to increase signal level so as to allow reception by several or even more receivers. The amplifier has the following inputs: FM+VHF band signal (88-108 MHz + 160-260 MHz) and 2xUHF band (470-862 MHz). The gain in the FM+VHF bands is 0...20 dB, while in the UHF band, it is 16...32 dB.
The AM-346 R903046 amplifier is equipped with 2 On/Off potentiometers allowing to send 24 VDC voltage and 50 mA current to the antenna preamplifier through each of the two UHF inputs.
Key features:
- 24 V/30 mA power supply
- 20 dB of gain in the FM+VHF band and 32 dB gain in the UHF band
- 2 On/Off potentiometers that allow 24 VDC voltage and 50 mA current to be sent to antenna preamplifiers through each of the two UHF inputs
- die-cast housing inside a compact plastic case
