Recently I boarded a KLM flight with an Embraer E175, when I noticed the strips on the nose

(see image, marked with the black circle). enter image description here Own image

This Embraer E190 also has it: enter image description here Image source

Whereas this A320 does not have it, is it an Embraer specific feature? What is it for? enter image description here

I believe this is a duplicate of another answer, but they are lightning arresters which conduct electrical charges away from the radome and avionics contained therein to the metal airframe where it can pass through and exit the aircraft without harm.

  • $\begingroup$ They're used more to discharge static buildup on the radome than handle lightning strikes. $\endgroup$ – Pheric Jul 9 '19 at 15:47
  • $\begingroup$ Well and what is lightning but a large static electric discharge? $\endgroup$ – Carlo Felicione Jul 9 '19 at 15:58
  • $\begingroup$ Fair enough. But the point is to not have a large static discharge at all $\endgroup$ – Pheric Jul 9 '19 at 16:06
