PREMIUM DX Commander Amateur Radio ALL BAND Vertical HF Antenna Portable Use

This listing is for the Ultimate Premium version of the DX Commander vertical. The Premium version includes everything you get with the economy experimenters version plus.

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). DX Commander pole of course! Ground plate with SO239 and flying lead. 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. 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, Ive 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 youll need to supply yourself are some guy stakes. Heavy Duty camping stakes are fine. Theres quite a following of DX Commander users out there, so join in and enjoy having a truly efficient multiband antenna. Of course a manufacturing error or fault is a different matter. 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.
