The GBS Elettronica Jolly line 45157/5G AMS2/2OUT 2U is a mains-powered VHF-UHF distribution amplifier designed for antenna systems that require signal splitting to two output points. Its integrated 5G filter suppresses transmissions in the 694–862 MHz range, ensuring clean terrestrial signal delivery as 5G networks roll out in the UHF spectrum.

Both the VHF and UHF gain stages are independently adjustable, allowing installers to balance signal levels between bands to suit each installation. A power LED provides immediate visual confirmation that the unit is energised.

Key Features

• Single input, two-output VHF-UHF line amplifier
• Built-in 5G filter covering 694–862 MHz
• Independently adjustable VHF gain: 8–23 dB
• Independently adjustable UHF gain: 8–23 dB
• F-type connectors on all ports
• Power LED indicator for operational status confirmation

Product Benefits

• The built-in 5G filter eliminates interference from 5G transmitters sharing the upper UHF spectrum, with insertion loss below 20 dB in the filtered band
• Independent per-band gain adjustment lets installers compensate for cable loss differences between VHF and UHF without external attenuators
• Two outputs allow a single coaxial feed to serve two receivers or distribution points without additional passive splitters
• F-connector standard ensures compatibility with all typical satellite and terrestrial coaxial cabling
• Mains power supply removes the need for external injectors or in-line power supplies
