Larsen NMO150BCO 144–174 MHz 5/8 Wave Base Loading Coil Only 

The Larsen NMO150BCO is a black, 5/8 wave base loading coil designed for VHF mobile antennas operating in the 144–174 MHz frequency range. This component is sold as a coil-only replacement or base part, meaning it requires a compatible whip (such as the W490B / 19616) and a standard NMO mobile mount to form a complete antenna assembly. It is commonly used in Land Mobile Radio (LMR), public safety, and two-way radio communications to provide enhanced impedance matching and tuning.
