The Jolly Line JL41049/2U (AL/300-2U) is a compact mains power supply built to feed pole-mounted TV amplifiers down the coaxial line. It plugs into a 230V outlet and outputs 12V DC at up to 300mA across 2 F-type connectors, with a 4dB attenuation across the RF signal path.

A front LED confirms power is being delivered, so you can verify the amplifier is energised without climbing to the antenna. It is the recommended companion to the Jolly Line JL45497/5G pole amplifier kit.
