The Johansson 7722L line amplifier amplifies and distributes terrestrial TV signals in the VHF and UHF bands, with one input and two outputs. Its built-in LTE/5G filter rejects interference from mobile networks. Gain can be adjusted independently for each band using a potentiometer.

The amplifier uses AC power, which can be supplied remotely, and an LED indicates power status. The unit can be mounted on a wall or DIN rail.
