Troubleshooting the KHF-950 System December 2013. If you are experiencing tuning and/or garbled transmitter problems with your KHF-950 system, you may have some outstanding Service Bulletins that should be installed. Honeywell and BendixKing: Creating the Future of General Aviation 'We get feedback from customers in lots of different ways,' said Neumann, Vice President of Operations and Product Support for BendixKing.

Yes, with the appropriate equipment, hardware, antenna, and installation considerations.
A shorted tranline often referred to as 'towel bar' antennas are best suited for helicopter applications. Towel bar antennas are attached parallel to the tailboom and fed in on the forward end (please see below example). Very specific instructions in relation to spacing, antenna construction, length, and mounting surface should be followed in order to minimize poor efficiencies at the low frequencies.
Since the towel bar style antenna is considered a short or shunt type HF antenna, the -02 version of the KAC-952 antenna coupler along with the KA-161 external capacitor must be utilized in this type of installation.
In certain installations, a towel bar style antenna may not be possible. Therefore, the KA-98 probe antenna may be used in the KHF-950 system. The same installation considerations (as mentioned above) would need to be observed since all short antennas provide poor efficiencies at low frequencies. A rod style antenna element is installed onto the front of the KA-98 (see picture below). It is important that the probe antenna be provided with a good RF ground. Therefore, the coax feedline from the KAC-952 coupler to the KA-98 cannot exceed 18 inches. In addition, the KA-98 can only be used with the -02 version of the KAC-952 and the KA-161 external capacitor to allow the antenna to tune more efficiently.
If this 18 inch requirement cannot be met, then the KHF-990 HF system should be considered since the amplifier is built in to the KAC-992 probe antenna coupler.
