4 Way Coax Remote Antenna Switch 500W RF for Radio Station

Discover effortless antenna management with the 4-Way Coax Remote Antenna Switch. Designed for radio stations, amateur setups, and multi-band broadcasts, this compact unit lets you switch between four inputs to a single radio output with a simple +12V control signal. Perfect for rooftops or towers, it eliminates the need to manually swap cables, saving time and reducing climb-related hazards while delivering consistent, high-quality transmissions.

Built for tough environments, it supports up to 500W continuous power (PEP) and uses low-loss signal transmission to maximize clarity and range. The robust construction combines ABS, PC, and metal components for durability during extended high-power use. With standard SO-239 connectors, installation is fast and hassle-free, letting you quickly integrate multiple antennas for multi-band and directional setups.
