The Ampro 30 is a helical-wound HF mobile whip antenna for the 30m band (10 MHz) — available in Moonraker and Sigma versions. Designed for mobile HF operation, the helical winding delivers full-size electrical performance in a manageable 245cm physical length, making it a practical choice for 30m mobile operation.Rated at 250W and with a VSWR of 1.5:1 or better, it's well suited to CW and digital modes commonly used on the 30m band. The 60 kHz bandwidth provides solid coverage across the band. The 3/8" thread fitting is compatible with the vast majority of mobile antenna mounts and magnetic bases.Key Features Type: Helical wound HF mobile whip Frequency: 10 MHz (30m band) Antenna length: 245cm VSWR: 1.5:1 or better Max power: 250W Bandwidth: 60 kHz Fitting: 3/8" thread Available in Moonraker and Sigma versions Technical Specifications Frequency: 10 MHz Type: Helical wound Length: 245cm VSWR: 1.5:1 or better Power: 250W Bandwidth: 60 kHz Fitting: 3/8" thread
