Doublers are used when antennas are installed to

Explanation:
When antennas are installed, the cutout in the skin creates a structural discontinuity that can concentrate stresses during flight. A doubler is a reinforced patch placed over or around that opening to restore the skin’s strength and stiffness, helping to distribute loads and prevent cracks or fatigue around the antenna area. This is why the primary purpose is to reinstate the structural integrity of the skin. Doublers aren’t about increasing antenna gain, reducing weight, or improving RF shielding.
