C‑Band Omni‑Directional 1/4‑Wave Antenna | 4.0–8.0 GHz

Product Description

This C‑Band omni‑directional aircraft antenna is a 1/4‑wave, vertically polarized radiator designed for broadband operation across the 4.0–8.0 GHz frequency spectrum. The antenna provides uniform azimuth coverage and stable electrical performance for avionics and aerospace RF systems requiring wideband C‑Band operation.

The antenna is matched to a 50‑ohm system impedance and maintains a maximum VSWR of 2.0:1 across the operating band, supporting efficient power transfer and minimized reflected power. Rated for up to 1 kW peak input power, it is suitable for high‑power transmission environments.

Engineered for aircraft installation, the antenna meets stringent FAA, RTCA, military, and environmental qualification standards, ensuring reliability under extreme temperature, vibration, shock, and exposure conditions.
