This listing is for the Premium version of the DX Commander vertical. Ideally suited to Christmas Presents, Birthday Presents and for those people who need a “plug-and-play” approach to their operating.
This Premium version includes everything:
- DX Commander Pole (of course)!
- 8 x Stainless hose clamps
- 75 cms 8mm id tubing
- 10 cms glue lined shrink-wrap (for creating the little end loops for fast take-down)
- 100m insulated wire (3 steel and 4 copper stranded in 2 x 50m runs), enough for 20 x 4m long radials and all your elements (you cut these yourself)
- Ground plate with SO239 and flying lead
- Driven Plate
- 8mm nylon guy plate (NEW! Up from 6mm)
- 5mm Upper Spreader (NEW! Up from 3mm)
- 5mm Double-Eye (NEW! Connects 30m and 40m elements. See YouTube videos) Last picture in Gallery
- Enough Nuts, bolts and connectors for 6 elements and 11 radial connectors
- 45 cms 3mm black shock cord
- 4 x element end loop connectors (may be duffle coat buttons or shock-cord ends depending on supply)
- 1m 3mm heavy duty guy line for connecting shock cord to upper spreader
- 6m 550 Paracord for guying your mast
The DX Commander vertical system is based on the same technique as a fan dipole. Effectively a number of elements present themselves to your load and self-select to achieve efficient quarter-wave performance on all bands, according to which quarter-wave elements are installed.
I run one of these myself and run 40m, 30m, 20m and 17m elements. The 15m band is also catered for by means of resonating the 40m antenna and uses what we have called a “boomerang” foldback to achieve a pseudo 5/8ths for 15m band. No tuner is required and the far field patterns are excellent for DX.
Achieving gain on 12m and 10m is simply a matter of clicking in your ATU on your radio since without appropriate quarter wave elements, you will find the SWR is only about 3:1. Quite reasonable. It will also tune on 6m and although the far field pattern is not perfection, there is gain and you will achieve Sporadic E contacts.
My own results have been very encouraging and I have really enjoyed deploying this antenna for /P and holidays. I even run one in my garden without any ATU via an amplifier.
Here are some example QSO recordings using this antenna:
Radials: There is much baloney surrounding the topic of radials. The bottom line is that the difference between around 15 radials and 120 radials is only about 3dB. Further, more and shorter radials are better than fewer and longer radials.
Personally, I’ve gone down a half-way house route with 35 x 4.5m long radials. These are crimped and soldered to a fork connector in bunches of 5 which means I effectively only have to make 7 connections when I set up.
You will need to invest in a relaxed “build day” to make your first build and solder your connectors on and measure out your element lengths to make sure the antenna is repeatable so that in future, you can erect within 20 minutes and pack away in a similar time. Tip: Tape the ends of the radials together when you pack away so they unravel fast in a single line without tangles.
The only thing you’ll need to supply yourself are some guy stakes. Heavy Duty camping stakes are fine.

There’s quite a following of DX Commander users out there, so join in and enjoy having a truly efficient multiband antenna. And don’t worry if you break it in a school-boy accident (walking on it, driving over it etc), I do replacement warranty poles for 66% of eBay’s price (inc shipping price). Of course a manufacturing error or fault is a different matter.

Buy with confidence. My ebay rating is 100% and I’m proud of that so if anything isn’t up to scratch, I’ll “do the right thing” and fix it for you. This is a hobby business with low margins, but I thoroughly enjoy making this gear and testing it out so that you get a great experience – and I get exactly the gear I want in the process.
