ME510 Gooseneck Electret Microphone Assembly - 25 in
This is a great electret microphone for use with Trig, XCOM, Flightline, and Microair aircraft radios. It is very rugged and classy looking. The right-angle mounting base and microphone adapter are black anodized machined aluminum parts - custom made for Cumulus Soaring, Inc. This gooseneck is a great value, yet it looks and works great in even the most expensive sailplanes. The sound quality is excellent.

Value Added
The cable supplied by the manufacturer with this microphone head is too short and too thick to fit through a gooseneck, so I have Larry Goddard replace the cable with a 12 foot long shielded cable. Also, the base of the microphone head is much wider than the end of the gooseneck, so I have a custom, black anodized, machined aluminum adapter made. It adds a lot. The right-angle mounting base is also a custom, black anodized, machined aluminum part.

This electret microphone works with Becker or Walter Dittel radios, but the TM170 dynamic microphone is a better value.

Color: All items are black in color to minimize reflections in the cockpit.
