A popular portable quarter-wave HF vertical for POTA/SOTA and travel, covering 40 through 6 m Quarter-wave ground plane on 20-6 m (14-50 MHz) using the 17 ft (5.6 m) stainless telescoping whip; the included 7 MHz coil adds 40 m Tuner-free operation on 20-6 m in normal use - you just set the whip to the laser-engraved frequency marking Self-contained kit: base with built-in ground spike (SO-239), four 11.48 ft counterpoise radials, the 40 m coil, the whip and a carry bag No tools needed - quick to set up and tear down in the field Laser-engraved whip markings make band changes fast and repeatable Rated up to 100 W, so it suits both QRP and 100-watt portable radios
Strengths

An efficient, fuss-free field vertical: a full-height 17-foot whip makes it a real quarter-wave on 20-6 m (more efficient than a short loaded whip), it needs no tuner there, and the engraved markings make band changes quick and repeatable. The kit includes everything - spike base, radials, 40 m coil and bag - sets up in minutes with no tools, and handles a full 100 watts. A deserved POTA/SOTA favorite.

Weaknesses

It is a ground-mounted vertical, so it needs the radials laid out and a clear spot to plant the spike, and at 17 feet the whip is tall to deploy in wind. The 40 m band needs the add-on coil, 80/160 m are not covered, and like any vertical it hears more noise than a horizontal wire up high.

Verdict

The Chelegance MC-750 is an efficient, quick-deploying portable quarter-wave HF vertical (40-6 m) with engraved whip markings and a complete spike-and-radials kit - one of the best field verticals for POTA/SOTA and travel, tuner-free on 20-6 m. Operators who want 80/160 m or an all-in-one no-radial system look at modular wire systems instead.

The Chelegance MC-750 (also branded JNCRadio) is a portable quarter-wave HF vertical that has become a favorite for Parks on the Air, Summits on the Air and travel. Unlike the short loaded whips many portable antennas use, it deploys a full 17-foot (5.6 m) stainless telescoping whip, which makes it a true quarter-wave on 20 through 6 meters - and a real quarter-wave is more efficient than a heavily shortened antenna. For those bands you need no tuner: you just extend the whip to the laser-engraved marking for your frequency.

It is a complete, self-contained kit. The base has a built-in ground spike that you push into the soil, an SO-239 for the coax, and jacks for the four included 11.48-foot radials that form the ground plane. An included 7 MHz loading coil adds the 40-meter band, so overall it covers 40 through 6 meters (7-50 MHz). Everything - whip, base, coil, radials - packs into a carry bag, and it goes up in minutes with no tools.

The trade-offs are those of a ground-mounted vertical: you need a clear spot to plant the spike and room to spread the radials, the 17-foot whip is tall to manage in wind, and the lowest bands (80/160 m) are not covered (40 m needs the coil). Like any vertical it also tends to hear more local noise than a high horizontal wire. It sells for around $130-160.

It competes with other take-along verticals such as the Wolf River Coils Silver Bullet 1000 and the modular Chameleon MPAS Lite, trading their tuner-and-coil flexibility for full-height quarter-wave efficiency on the higher bands.
