The GBS Elettronica Jolly Line JL45159/5G is a mains-powered VHF–UHF line amplifier with 1 input and 4 outputs. It covers VHF frequencies from 47 to 230 MHz and UHF from 470 to 790 MHz, and includes an integrated 5G interference filter that suppresses frequencies in the 694–862 MHz 5G band.

Gain on both VHF and UHF bands is independently adjustable between 5 and 20 dB, allowing the installer to compensate for cable losses in each run. A power LED provides clear status indication.
