As the only official service facility that can certify the ANT-67A TCAS antenna, Honeywell does not and will not refurbish a used ANT-67A antenna. Southeast Aerospace will make an effort to clean up and improve the appearance of the used antenna. However, if the lower priced Serviceable (not New) ANT-67A is desired, then please note the appearance of the unit may be the same as it was when removed from the aircraft.
