The Jolly Line 41049 AL/300 1U supplies 12 V DC through a coaxial cable to a connected antenna or mast amplifier, eliminating the need to run a separate low-voltage cable to the amplifier installation point. It is confirmed compatible with the Jolly Line 45129 CST/VU2 2-output mast amplifier with LTE/4G filtering.

The unit connects to the mains at 230 V, delivers its output through a standard F connector, and includes an LED indicator to confirm power delivery status. Its 4 dB insertion attenuation applies to the RF signal path.
