Heil HMM-DYN
Dynamic Element

  Out of stock  

The Heil HMM brings new technology to the hand microphone. No question when you place a microphone element inside a clam shell. The result is a hollow muffled sound but Amateur Radio operators have lived with it for decades. To solve this problem, Heil installed a grill on the top of the microphone that detunes the internal resonance of the housing. Heil designed a very special full range microphone element with great speech articulation. The result is a phenomenal hand microphone. Cardioid pattern, 600 ohms unbalanced, 6.5 ounces.

A very flexible, but sturdy coil cable terminates as all of our headsets with 1/8” male for the microphone and a ¼” male for the PTT control. This would then plug into the required appropriate AD-1 cable, sold separately. See table below.

The Heil HMM-iC is strictly for select Icom radios and will also require the AD-1-iC or AD-1-iCM cables that do not have the DC blocking capacitor.
