5.8GHz RHCP FPV Antenna | ANT58M 3dBi Circular Polarized UAV Video Transmission Antenna | SMA Connector
Category: FPV & Imaging System, VTX Antennas
The ANT58M 5.8GHz FPV antenna is designed for UAVs and FPV systems requiring stable, low-loss, and interference-resistant video transmission. With 3dBi gain, a wide 4990–5945MHz operating range, and RHCP circular polarization, it ensures consistent signal quality for both short- and mid-range flight scenarios.
Its lightweight, durable build and SMA connector make it easy to integrate into racing drones, long-range quads, and fixed-wing FPV aircraft. The optimized vertical beamwidth delivers balanced penetration and broad coverage during dynamic maneuvers.
