Introduction The Elecraft AX1 is a compact telescoping whip that disassembles into 6” (15 cm) pieces, so it will fit into small “grab & go” bags... or your back pocket. On the basic unit, a two-position switch selects 20 meters (resonant) or 17/15 meters (a low-loss match can be achieved using an antenna tuner on both bands).
NOTE: In cases where it is difficult to achieve a low SWR (< 3:1), transmitting may still be possible at reduced power. Elecraft transceivers can be safely used at high SWR.
Attach the wires to the transceiver via a BNC-to-binding post adapter, such as our model BNC-BP. Elecraft ATUs will usually match this efficient antenna on 40 through 10 m.

To set up the AXE1: • Attach the supplied 33 ft (10 m) radial wire to the transceiver at a point near the antenna jack. The Elecraft KX2 and KX3 provide thumb screws for this purpose. (The AX1’s 20/17/15 meter radial and the AXE1 radial may both be connected to the rig at the same time.)
Counterpoise The counterpoise (or radial) wire supplied with the basic AX1 is usable on all three covered bands (20, 17, and 15 meters). The Wires two inductors in the base unit have been adjusted to provide resonance close to the 20 meter band with this radial length. The AXE1’s longer counterpoise wire is usable on 40 and 30 meters.
