Lightning Punctures JetBlue ERJ-190 Nose Radome

It appears the Embraer ERJ-190 radomes are susceptible to lightning punctures.  The following pictures show a recent lightning strike.

The metal bar diverters on the ERJ-190 do not extend far enough forward to protect the radome tip.  This is a common problem as metal bar diverters degrade the RF signal of the weather radar.  To compensate, the metal bar diverters are kept short and out of the radome’s RF window.

Many radome manufacturers have solved this problem by installing WXGuard lightning diverters from the ends of the metal bar diverters to the tip of the radome.  WXGuard segmented lightning diverters are RF transparent, rain erosion resistant and are a perfect solution to reduce costly radome punctures.
