There is no physical, technical, or functional difference at all between the Sensor Systems S67-2002 and Honeywell KA-54A antennas. Honeywell (Bendix/King) obtains the antennas from Sensor Systems, labels it with Part Number 071-01501-0000. In fact, Honeywell even lists the generic Sensor Systems P/N S67-2002 as a recommended antenna for the KRA-405B radar altimeter system. Please see this excerpt from the KRA-405B installation manual.

If an intermittent noise problem exists, then it is strongly recommended to use only non-magnetic stainless steel screws when mounting the KA-54A antenna. As an example of such a screw is P/N MS24693-C272.
The arrows on some radar altimeters are a reference reminder that the antennas must be mounted on the same longitudinal axis on the aircraft. Normally, the antennas are mounted so that the arrow head of one antenna points to the tail of the other antenna arrow. The 2 arrows can point at each other as long as they are on the same longitudinal axis. Click here to view a basic diagram of proper radar altimeter antenna installation.
