I purchased this to use on an experimental after installing a GTX-327 and not realizing that the original monopole antenna was not compatible with the 327. This one had the quickest shipping of all blade antennas on aircraft spruce. red tail or E05 would have worked fine otherwise. This antenna passed the transponder test on the first attempt.

Was wanting to purchase Comants Experimental version of this Transponder Antenna but there was a long waiting time so I opted for this more expensive certified model. At $160 think it’s bloody mean of Comant to NOT include the washers and nuts for installation.
