ALCAD Masthead Amplifier 1 input, UHF, 24dB Gain (12v dc)

Application

The AM-112 amplifier is used as a mast device. It can be applied as an amplifier in small antenna installations of a few sockets. It is used when the signal level is too low, or to compensate the loss caused by the cable's length between the antenna and the rest of the installation (e.g. inputs of CA-210 amplifiers). Due to the fact that the device has to be fed with 12 V voltage, it must be remembered to use the proper power source.

An interesting thing about the amplifier is the fact that it has an additional output with the level set 15 dB lower than the main output. It can be used with ease to couple a measuring device during the amplifier's regulation and positioning the antenna, or to connect additional two sockets.

Installation and security notes

AM-112 amplifiers are fed through a coaxial cable with 12 V voltage, from a stabilized power supply with DC separator. The amplifier is designed for mast mounting, and it can work in open spaces. To avoid any possible damage the power should not be switched on until all connections are made properly. It is advised to use the AL-105 (R903087) or ZS 12/100 (D0010) supplier.
