The Jolly line 45973-EU is a multiband amplifier engineered for central antenna distribution facilities handling digital and analogue terrestrial channels. Its aluminium die-cast chassis and GaAs-MMIC transistor technology deliver high linearity and efficiency in a compact form with low power consumption.

The amplifier features an integrated 5G filter (694–862 MHz) to prevent 5G mobile signals from interfering with UHF reception, a test output at -30dB, and front-panel attenuators for level adjustment. It carries European certification.
