Several years ago we had a Winegard antenna installed on our home. The installers put a small signal booster on it. The model number on it is a PS-9370. I think this unit may already be discontinued, but I was wondering is there a similar power supply I could use to replace this one with without having to climb on the roof and replace the other part of it?
The PS-9370 power supply merely sends 15 volts AC up the coax cable to power the amplifier. The actual amplifier is located at the antenna. You can check the antenna connector on the PS-9370 with a volt meter to check that it is putting out the 15 VAC. If you need a replacement power supply the model number is PS-1503.
