The Jolly Line 45163 AMS2/RF 2U is a two-output line amplifier covering both VHF and UHF bands with independently adjustable gain for each band. Its integrated 5G rejection filter blocks frequencies from 694 to 862 MHz, preventing interference from 5G mobile networks on terrestrial TV reception.

Designed for indoor antenna distribution installations, the amplifier uses F-type connectors and operates on standard 220–230 V mains power, making it straightforward to integrate into existing coaxial signal networks.

Key Features

• 1 input / 2 outputs configuration for splitting the signal to two outlets
• Adjustable VHF gain: 10–25 dB
• Adjustable UHF gain: 15–30 dB
• Built-in 5G filter rejecting 694–862 MHz with insertion loss below 20 dB
• F-type connectors on all ports
• Power LED indicator for at-a-glance operational status

Product Benefits

• Independent VHF and UHF gain controls let you fine-tune signal level to suit local conditions
• The 5G filter prevents picture breakup caused by adjacent 5G network interference
• Two outputs allow distribution to two separate TV points from a single antenna feed
• 75 Ohm impedance matches standard coaxial antenna systems directly
• Low noise figure (4–5 dB) preserves signal quality after amplification
