The Johansson 7724L2 line amplifier amplifies and distributes VHF/UHF signals to four outputs via a single input covering the 40–320 MHz and 470–694 MHz bands. Its built-in LTE/5G filter suppresses interference from mobile networks above the TV UHF band. The gain for each band can be adjusted independently using potentiometers.
The 24 VDC remote power supply can power a masthead amplifier via coaxial cable. An LED indicates the power status, and the device can be mounted on a wall or DIN rail.
