Convert a Military Helicopter Helmet for Civilian Helicopter Use

Convert a Military Helicopter Helmet for Civilian Helicopter Use

Converting a Military Helicopter Helmet for Civilian Helicopter use is very easy. Military and civilian radios and intercomms operate on different impedances, but the both military and civilian helicopters use the same U-174 plug on the helmet cable. This means that military helicopter helmet cables are compatible in civilian helicopters. That just leaves the microphone and earphones that need to be converted. This can be done with one of the following methods:

  Replace your military impedance microphone and earphones with civilian impedance microphone and earphones. This option is recommened if the helmet only needs to operate in civilian impedance aircraft. Click here to purchase.

  Use an impedance converter and keep your existing microphone and earphones. This option is recommended if the helmet needs to remain compatible with both military and civilian impedance aircraft. Click here to purchase.
