The Ampro 10 is a helical-wound HF mobile whip antenna for the 10m band (29 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 10m mobile operation.Rated at 250W and with a VSWR of 1.5:1 or better, it's well suited to SSB, FM, and digital operation on the 10m band — one of the most exciting HF bands during solar maximum, with the potential for worldwide DX contacts. The wide 500 kHz bandwidth provides excellent coverage across the full 10m band without retuning. 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: 29 MHz (10m band) Antenna length: 245cm VSWR: 1.5:1 or better Max power: 250W Bandwidth: 500 kHz Fitting: 3/8" thread Available in Moonraker and Sigma versions Technical Specifications Frequency: 29 MHz Type: Helical wound Length: 245cm VSWR: 1.5:1 or better Power: 250W Bandwidth: 500 kHz Fitting: 3/8" thread
