Applications
The CA-210 amplifier is used as a signal distributing device in small antenna installations, to ensure proper levels of signals for multiple receivers. The amplifier works in 40–400 MHz and 470–862 MHz bands. Thanks to separate gain adjustment for VHF and UHF band, the signal levels can be set independently in each of the bands. This makes it easier to set them properly in installations combining signals from all antennas to send them via one cable.
The amplifier can be used in shared antenna systems. Due to a gap between VHF and UHF bands (S20-S38), it cannot be used in typical cable TV systems. The amplifier is especially useful in situations where original signals are low (it can additionally power preamplifiers).
Security notice for amplifier users
CA-210 amplifier is fed from internal stabilized power supply. It is not designed for the use in open spaces. It cannot be installed in wet conditions, nor near heaters. Providing natural ventilation is a must. To avoid any possible damage, power should not be provided until all the connections are made properly. The amplifier allows to feed preamplifiers with 24 V voltage, and maximum current of 55 mA, e.g. Alcad mast preamplifiers.
