One or two rotators may also be selected in combination with the antennas. One synchro transmitter for tower mounting to feed the beam direction indicator is included with the SC-101. The synchro receiver is an integral part of the direction indicator. The 68Y-1 mounts in any convenient position near the station. It contains the antenna transfer relay, two coax relays for antenna selection, mounting bracket for the directional wattmeter coupler and necessary interconnecting coax cables.
Space is provided for mounting three additional coax relays.
The 534A-1 includes a metal duct which mounts on the rear of the desk or table and houses all interconnecting cables. Utility AC outlets are provided along the top of the duct. Additional standard conduit will be needed in lengths depending on the individual station installation. It utilizes a hybrid transformer for proper VOX operation. Output impedance is 600 ohms.
