DX Commander Vertical HF Antenna Multi-Band All-Band Bundle Price

This listing is for a DX Commander Pole and the Conversion Kit plates only. The DX Commander vertical 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 using a boomerang element 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. Alternatively, fit elements for 12m and 10m. 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 negligable. Further, more and shorter radials are better than fewer and longer radials. And I made this video too. Personally, Ive gone down a half-way house route with 20 or so x 4.5m long radials in bunches of 5. 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. One for just above the driven plate and one to attach your 30m element to. Ground plate with SO239 and flying lead. Alternatively go for the full 9-yards listing. 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. I have measured the element lengths from mid-way between the fork connector and the end of the blue section. To avoid confusion, it is effectively exactly the same length of the wire as follows.

17m - 3.83m + 6 cms foldback (for the heat shrink). 20m - 4.88m + 6 cms foldback. 30m - 6.74m + 6cms foldback. 40m (and 15m) - 11.06m (no foldback) (Physically, a 5/8ths for 15m). If you want to tune 15m higher in the band, cut about 15 cms off the 40m element.

It will make only negligible difference to the 40m band SWR curve but will raise the 15m band SWR by around 100 KHz. 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.
