The Drake Model CS-7 Coax Switch
accessory capable of remotely switching up to five (5) coax-fed
antennas via one
(1)
main coax feed line. In addition, the
internal local switch allows switching of up to five (5) radios;
either transmitters, receivers, or transceivers
feed line. This minimizes the amount of coax needed for
antenna installation, plus provides grounding of unused inputs
both local and remote. The CS-7 is housed in an attractive
enclosure styled to match the Drake 7-line equipment.
