Abstract: A switch includes: an HPA bypass switching component that can be in an HPA bypass state and an HPA state and an HPA switching component that can be in the HPA bypass state and the HPA state. When the HPA bypass switching component is in the HPA bypass state, the HPA switching component is in the HPA bypass state. When the HPA bypass switching component is in the HPA bypass state and the transceiver is generating a transceiver transmission signal, the transceiver transmission signal is provided to the antenna and the received transceiver transmission signal is provided to the transceiver. When the HPA bypass switching component is in the HPA state and the high power amplifier is generating an HPA transmission signal, the HPA transmission signal is provided to the antenna and the received HPA signal is provided to the transceiver.

Abstract: A fire extinguishing system for a Christmas tree including a base defining a water reservoir and having a submersible pump and container holding a fire extinguishing foam material mounted in the reservoir. A venturi block mixes the fire extinguishing foam material with water pumped from the reservoir upon detection of a fire condition by sensors scattered throughout the tree which mixture is discharged through a spray head mounted at the top of the tree. A relay connected to the fire sensors simultaneously closes an electric circuit to the pump and opens an electric circuit to the Christmas tree lights when the fire condition is sensed.
