DX Commander Expedition Portable HF Multi-Band Vertical Antennas

DX Engineering is currently shipping the new 2024-Spec DX Commander Expedition Antenna kits

DX Commander Expedition Portable HF Multi-Band Vertical Antennas are an excellent choice for DX performance and general operations. Efficiently resonant on every HF band of operation, featuring wide SWR bandwidth and low take-off angle, the Expedition covers the Amateur bands 40 to 6 meters. DX Commander vertical antennas are based on the same principles as a fan dipole, with several vertical wire elements of various resonant lengths connected to a common feedpoint. The wire elements and support ropes are arranged with spacer plates around the non-conductive fiberglass mast. When installed with an appropriate radial system, the Expedition achieves efficient quarter-wave vertical performance with natural resonance and low SWR on every band, without the need for traps, coils or antenna tuners. Band-hopping DXing and simultaneous multi-band multiplexed operations are supported. The Expedition antenna is rated at 1500W SSB/CW, 400W FT8 and other digital modes.

The DX Commander Expedition portable mast includes additional telescoping sections that make up the entire 30.18 ft. (9.2m) mast. The mast is only 2.13 ft. (65cm) long in its fully collapsed position for easy portability and will easily fit into a backpack. The main section of the mast has the same external diameter as the “Classic” mast, which means that each section has a lower wall-thickness with higher overall flexibility. The Expedition includes a new and improved screw base and stronger components.

This is the NEW 2024-Spec Expedition Antenna kit includes Speed Slots, Screw Base and quick-release elements for fast deployment and tear-down.

DX Commander Expedition Features and Specifications:

Alloy Plates: Aircraft-quality 5251 alloy, laser cut in England before deburring to give that “hammered” look, which eliminates sharp edges and provides a nice finish.

Spreader Plates: Marine-grade high-density polyethylene sheet material from USA, charcoal-gray, UV and environmentally stabilized to withstand the harshest of marine and high RF conditions. Spreader Plates are machine cut in England to DX Commander specifications which now include Speed Slots.

Stay-Up Kit: Band style clamps, that keep the antenna mast sections extended, are molded in England in a black PA66 Nylon. Supplied in Hex or Wing Nut version depending on antenna model.

Shock-Cord: Marine grade shock-cord, with a UV and RF stable Dyneema woven exterior.

Spade Connectors: Kits include large spade connectors for best performance under tension.

Hardware: All nuts, bolts and washers are stainless steel.

Coaxial Connector: UHF female SO-239 coaxial connector, nickel plated brass with PTFE dielectric.

Fiberglass Poles: Made to DX Commander specifications in a spiral wound fiber, high-quality epoxy and paint finish.

DX10 Wire: Made in England for DX Commander, DX10 wire has an outstanding reputation for both strength and in particular, extreme flexibility. The insulation is “arctic grade” and still flexible down to -40° F. Originally designed for military use, this insulation is particularly strong but highly flexible and the stranded annealed copper wire is approximately 19 AWG and is made from 24 strands of 0.008 in. (0.2mm) wire.

SWR: The Expedition can deliver a curve with the 1.5:1 SWR points beyond most band edges, except 10m which has a 2:1 bandwidth of about 300 kHz. On 40m, 30m, 20m, 17m, 15m and 12m, band edges are better than 1.5:1, with the best SWR typically at 1.1:1. Each band is adjustable to achieve the lowest SWR at either CW, FT8 or SSB frequencies. 6m SWR is not guaranteed due to variations in surroundings.

DX Commander antenna kits now include improved HCL EZ-Clamps and Dyneema Shock Cord instead of Carabiners.
