The Jolly Line 45979/5G-EU is a compact UHF multiband amplifier built for central antenna head-end installations. It accepts two independent UHF inputs and combines them into a single output, providing 30 dB of gain per channel across the 470–694 MHz terrestrial broadcast band. The integrated 5G filter attenuates signals from 694 to 862 MHz, protecting the TV distribution network from mobile network interference.

The amplifier operates from a wide-range AC supply (90–250 Vac) and includes automatic 12 Vdc tele-power feed for remote powering of upstream components. Power consumption is 2 W. European certification is included.

Key Features

• Two independent UHF inputs, one combined output
• 30 dB gain per UHF channel (UHF 1 and UHF 2)
• UHF operating frequency: 470–694 MHz
• Integrated 5G filter: attenuation >20 dB from 694–862 MHz
• Integrated 4G filter coverage: 694–790 MHz
• Adjustable gain per UHF band: 10–30 dB
• Maximum output level: 115 dBµV
• Automatic tele-power supply: 12 Vdc / 90 mA

Product Benefits

• The 30 dB per-channel gain compensates for cable losses and signal splitting in medium-scale distribution networks
• The built-in 5G filter prevents LTE 700 band interference from degrading UHF channel reception without requiring a separate external filter
• Two independent UHF inputs allow combining signals from two separate antenna positions or frequency groups at a single head-end point
• Automatic tele-power feed eliminates the need for a separate power injector for remotely powered antennas upstream
• Wide-range AC supply (90–250 Vac) ensures compatibility across different mains voltages without modification
