We are offering this design in two kits.

The QX1 Antenna kit, is a small, ultra portable vertical 40m, 20-10m antenna with a male BNC connector and telescoping whip, rated at 20W. It is resonant on the whole 40m band with only a whip length adjustment. With a tuner, can be used on the 20m through 10m.

All the holes are pre-drilled and tapped. Assembly requires winding the coil, a little soldering, and some mechanical assembly. The tools required for assembly are a Phillips screwdriver, forceps or needle nosed pliers, wire cutters, soldering iron, and some rosin core solder. Depending on your experience, it can be assembled in about an hour. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 2.

The BNC Antenna Mount/Adapter kit is a versatile antenna mount with a nylon clamp included. This design allows small BNC terminated antennas to not mount on the output connector of the radio, but rather, with coax, to a more advantageous position. It is ideal for quick setup, field and SOTA operation. We have listed this as a separate kit because, some users already have an antenna like the Elecraft AX-1, MFJ-18xxT series, or similar homebrew antennas that are terminated with a male BNC connector. The strong clamp permits mounting to a apartment or patio railing, picnic table, or even a tree branch. There is a connection point for radials or a counterpoise with captive stainless steel hardware.

Assembly is easy and only the most common tools are needed and a 1/4″ drill. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 1.
