The Drake Model CS-7 Coax Switch manual provides detailed instructions for setting up and operating the switch, which can remotely manage up to five coax-fed antennas and radios through a single main coax feed line. It also includes troubleshooting tips, such as ensuring proper grounding and voltage selection, to ensure optimal performance and prevent damage during operation.
Manual Overview
The Drake Model CS-7 Coax Switch is designed for remotely switching up to five coax-fed antennas through a single main coax feed line, and it also allows for switching up to five radios (transmitters, receivers, or transceivers) to the main coax feed line. This setup reduces the amount of coax needed and provides grounding for unused inputs. The unit supports a maximum input power of 2000 Watts PEP and operates within a frequency range up to 150 MHz. Installation involves connecting the antenna switch to the console using an 8-conductor cable, ensuring proper grounding, and using 50-ohm coaxial cables with PL-259 connectors for all connections. For operation, select the appropriate voltage range (120 VAC or 240 VAC) and ensure the correct fuse rating. The unit is energized when the “ON” lamp is lit. Antennas are switched by rotating the remote switch, and the “STANDBY” light indicates the motor-driven switches are active. Proper grounding and connection practices are crucial for optimal performance and safety.
Quick Issues Covered
- Diagnoses power-up failures with 'ON' lamp indicator.
- Troubleshoots antenna grounding issues via terminal connections.
- Calibrates voltage settings for 120/240 VAC operation.
Overview
The Drake Model CS-7 Coax Switch is a versatile accessory designed to remotely switch up to five coax-fed antennas via one main coax feed line. It also allows for the switching of up to five radios, including transmitters, receivers, or transceivers, to the main coax feed line. This setup minimizes the amount of coax needed for a multi-antenna installation and provides grounding for unused inputs both locally and remotely. The CS-7 is housed in an enclosure styled to match the Drake 7-line equipment.

Installation / Setup
The installation of the Drake Model CS-7 Coax Switch involves several key steps. First, carefully remove the unit from the shipping carton and check for any damage. If damage is found, notify the transportation company and keep the carton and packing material. The antenna switch can be mounted using a universal bracket to a tower or flat surface, and it features “RAIN-HAT” construction for adverse weather conditions. Connect terminals #1 through #8 on the antenna switch to the console using an 8 conductor cable, and use a cable clamp to relieve strain. It is recommended to coat the terminal strips with silicone sealer or RTV after connecting the cable. Grounding is necessary, either to a good earth ground or the tower, to ensure proper antenna grounding. Connect antennas to the coax receptacles on the antenna switch using 50 ohm coaxial cable and PL-259 connectors, and record the receptacle numbers for each antenna. Connect the single transmission line to the coax receptacle labeled “C” on the console. Connect receivers, transmitters, or transceivers to the other coax receptacles, and record the receptacle numbers for each radio.
Operation
Determine your particular line voltage and select the proper voltage range on the rear panel, either 120 VAC or 220 VAC/60 Hz. Be sure to change fuse ratings if the voltage range is changed. When the ON-OFF button is depressed, the “ON” lamp should light indicating the unit is energized. The remote switch determines which antenna is terminating the transmission line. To change antennas, merely rotate the remote switch to the desired number or description. The standby indicator will light showing the motor driven switches are turning. When the “STANDBY” light goes out, the antenna selected is terminating the transmission line. When leaving the station, return the ANTENNA SWITCH to GND. After the “STANDBY” light goes out, depress the power switch and note the “ON” lamp goes out.

Safety & Warnings
CAUTION: Ensure the transmitter is in the “off-the-air” condition when the standby light is lit continuously, indicating motor-driven switches are turning. During this interval, the transmission line is improperly terminated.
