Elecraft AX1 Mini Antenna ~ SWR Analysis & Testing

Using the AX1 with an ATU eliminates tedious length adjustments. Just select a band, tap the antenna tune switch, and go for it. The AX1 is resonant on 20 meters in one switch position, while the other is designed for efficient 17 and 15 meter matching using an ATU.

Whether you use the AX1 as a ‘stealth’ field antenna, for pedestrian mobile, or as a versatile backup, it’ll be ready when you are.

Resonant Frequencies
20 m (~14 MHz) and 17/15 m (~19 MHz). Resonant frequencies may vary +/- 300 kHz or more due to changes in terrain, body capacitance, and antenna height.
Supplied Radial Wire 13 feet (4.0 m) long. Wire has pre-installed lug for attachment to the transceiver’s ground screw.
Max. Power
30 Watts. If RFI symptoms are observed, reduce power or move antenna farther from the transceiver.
