Page 2: Installation
Introduction: The SDC-105 Screwdriver Antenna Controller will automatically adjust the screw driver antenna to the Transceiver’s frequency. The controller senses RF an automatically moves the antenna to the correct location. The controller has a two speed motor control for reaching the desired location in less time. There are no cables to connect to the transceiver. - Page 3 The mate can be order thru Ameritron part number 13-TAR102-2. Or the plug can be cut off and hard wire to the antenna. See pictorial for wire color and its functions.
- Page 4 Important: Failure to adjust and operate your screwdriver antenna at the proper voltage will damage the antenna motor. If a dropping resistor is necessary, a good value to try is 5 Ω/10 Watts. This resistor will need to be placed inline on one of the motor control lines anywhere in between the controller and the antenna.
- Page 5 Note: The counter will not count below zero. The antenna will continual moving but the counter will stay at zero if the antenna is not at it lowest location. Notice the direction of the antenna when pressing the UP button. If the antenna is going the wrong way the polarity can be changed in the menu or the motor wires can be swapped.
- Page 6 4. After the antenna is tuned to the correct position. Verify the display is showing the Transceiver’s frequency and the P is showing the turns of the antenna. 5. Press the SETUP button until the word STORE appears. 6. Momentary press the ENTER button. The display will read the Band and memory location 1 in the bottom right of the display.
- Page 7 Note: RF has to be present during the whole tuning for Low VSWR process. If the Sensor losses RF the controller will assume the VSWR dropped below 1.5:1 and stop tuning. Auto Mode the controller will automatically move the antenna to the stored location without having to press the TUNE button.
- Page 8 TRIP The controller has a current limit to help prevent the antenna’s motor from damage. When the current reaches the programmed setting it will turn the motor off. This is a good way to protect the motor from motor stall when the antenna is all the way at the bottom or top.
- Page 9 Trouble Shooting: Controller does not count but antenna moves up and Down An. 1. Check the plug for loose connection. 2, Need to determine if it is the antenna or controller. Disconnect the antenna’s control cable from the controller. Take the end of the cable going to the controller.
