Ampro 20 HF Mobile Whip Antenna 14 MHz, 250W, 245cm, 3/8" Thread

The Ampro 20 is a helical-wound HF mobile whip antenna for the 20m band (14 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 20m mobile operation.

Rated at 250W and with a VSWR of 1.5:1 or better, it's well suited to SSB, CW, and digital operation on the 20m band — one of the most popular HF bands for mobile operators. The 150 kHz bandwidth provides generous coverage across the band. The 3/8" thread fitting is compatible with the vast majority of mobile antenna mounts and magnetic bases.
