The EME168 Series 2m / 1.25m / 70cm Band RX/TX bias tee Kit is suitable for powering the Mini-Kits 1.25M band EME220-1.25M, 2M band EME220-2M or 70CM Band EME237-70CM Pre-amplifiers via the coaxial cable. The design has been optimized to cover the complete 100MHz to 500MHz frequency range for the lowest loss and return loss. The board is fitted with PTC protection to safeguard against any short circuits on the RF/DC output, and over voltage.  Transceivers with an accessory connector usually have a positive voltage, or grounded logic TX output that can be easily connected to the Bias Tee to control the switching. The Bias Tee is designed to handle up to 500 Watts CW. For more information see the EME237-70CM Application Block Diagram

Please select the connector types that you require for both the RF connection to the receiver, and the RF/DC connection that goes to the amplifier.
