If you’ve ever gazed out of an airplane window and noticed small metallic spikes protruding from the wings, tail, or top of the fuselage, you’re not alone. These little features often raise questions—from casual curiosity to professional interest.
So what are these “little spikes”? Are they lightning rods? Are they antennas? Do they help the plane fly? In this article, we’ll demystify their purpose, explain the difference between static dischargers and aircraft antennas, and offer expert advice for selecting aviation-grade RF components.
First Things First: What Are You Seeing on a Plane?
Airplanes have a wide array of external protrusions, but the “spikes” you commonly see fall into two categories:
Static dischargers (also known as static wicks)
Communication or navigation antennas
Common Locations for These Spikes
You’ll typically spot these devices in the following areas:
Wing trailing edges
Horizontal and vertical stabilizers
Top of the fuselage
Near antenna domes or communication bays
Knowing where to look gives you a better chance of identifying their purpose.
Compact RF antennas suitable for aircraft fuselage or UAV platforms
Shielded coaxial cables and connectors for high-reliability communication
Custom-built solutions for aerospace-grade applications
We work with aerospace integrators, OEMs, and MRO teams to support both standard and tailored deployments.
Common Misconceptions
Misconception
Reality
“They’re lightning rods.”
False. They manage static discharge, not direct lightning.
“All spikes are antennas.”
False. Many are passive dischargers.
“Removing them won’t matter.”
False. It may impact flight safety and system performance.

Looking for RF antennas, cables, or connectors for aircraft or UAV applications?
We offer tailored solutions, technical support, and global shipping.
1. Are those spikes dangerous to touch?
No, they are safe and static dischargers don’t carry active current on the ground.
2. Do all planes have static wicks?
Most modern fixed-wing aircraft do, especially those with composite materials.
3. Can antennas and dischargers interfere with each other?
Not if properly designed. They follow strict installation spacing standards.
4. How often do these parts need replacement?
Static dischargers are wear-prone and replaced more frequently than antennas.
5. Can Bafitop supply static dischargers too?
While our specialty is in RF antennas and connectors, we can advise or source equivalents based on specifications.
