Antenna Control Units

TAC-2 Control Box
Used to switch between two antennas, with "right", "left" and "both" positions. Typically used to combine two antennas or switch between antennas mounted on right and left struts of aircraft to aid in aerial location of transmitter. Warranted for 100,000 operations.
TAC-7 Control Box
Used to switch between two antenna, with "right", "left", and "both" positions. In addition to switching between left and right antenna, there is an added capacity to switch a third (auxiliary) antenna, typically used for omni-directional signal finding. Has option of plugging in a remote (yoke-mounted) toggle switch to select between the left and right antennas. Toggle switch (e.g. TPT-1 or TPT-2) not included.
TAC-4 Two-Port Peak Combiner/Splitter
Zero-degree phase shifter (combines two 50 ohm signal sources and provides a matched 50 ohm combined output). Used for precision peak systems in which signals received by two antennas are additive, providing a maximum signal when antennas are pointed toward the signal source. The TAC-4 may also be used to split an incoming signal from an antenna system for the simultaneous use of two receivers.
