DX Commander User guides


7mDXC LITE User Guide Mistake. There is no “double eye”, only an Upper Spreader Plate (triple top plate). I will amend this shortly. Thanks. Callum.


10m ABV Classic now has new hole spacings on driven (and the nylon plates) for equidistant spaced 3, 4 or 6 elements. See updated manual (April 2019).

Hose Clamps: In the main, you will normally end up with 8-clamps (sometimes 7). Use the largest one for the very bottom – and work your way up the pole (after slipping on an appropriate length of tubing over it).

Important Build Notes 10m All Band Vertical Classic (June 2018)

There are generally very few issues that builder have when assembling the DX Commander ABV system. If they do have issues, in the main slowing down and taking a break fixes almost all of them! And remember, if something genuinely isn’t right, I’ll replace it FOC (anywhere in the world).

Please remember, that this whole system is an experimental bit of fun. You can get it right and laugh in the face of $1,500 antennas whilst maintaining pureness in terms of tuned quarter-wave elements (5/8th in the case of 15m band). Please have some empathy for the crazyness of this project. Many (MANY!) people have an absolute ball with this system and understand that it it what it is, a fibreglass pole, some cut plates and a few nuts and bolts. But antennas don’t need to be expensive – it’s only an engineering solution to holding bits of wire up in the air.

But to make this a true production piece of “hardened” engineered solution, it would cost just as much as a SteppIR’s (BigIR Mark IV Vertical 40m-6m). Instead, this is cheap and cheerful – but with the same performance. Instead of a single element that varies in length, we nest each element like a fan-dipole.

So, save yourself nearly $2,000..!

D10 Complimentary Wire: I ship just over 100m of wire with all All-Band-Vertical orders. This is cheap-and-cheerful wire. Feel free to use your own. A reel of very nice flexible wire is just a few dollars (pounds) on eBay (for instance). In testing, D10 will happily accept 1500W key-down, full duty cycle RF for HF (tested with appropriate permit from Ofcom). The fire which you may have heard about was caused by a customer using 1000W of FT8 with the BLACK plastic plates which absorb RF slightly (not noticable below 400W). Regardless, 100% duty cycles (RTTY / FT8) is extremely hard wearing on all your equipment – be careful.

Unraveling the bunch of D10 wire. If I have supplied any old-stock D10 wire – just find the end of the wire and remove the insulation tape from the roll I send to you. Ask your partner (or closest tree) to hold the end of the D10 and walk away, turning the D10 like a wheel away from you. Basically, just unwind it. D10 is EXTREMELY tough wire that is double-sheathed and has four tinned copper and three tinned steel wires. Because of this, it has some “memory”. but once it’s unwound, you can deal with it. To split the pair of wires, connect a battery drill and unwind from one end in a clockwise manner. Be careful though because you are now inducing another spin into each wire, so when you feel you have done enough, don’t just drop the now unraveled D10 to the floor. Instead, grasp each one and hold them apart whilst they “unspin” in your hands. You’ll get it :)

Permanent fixing: Many have done it successfully. Use some self amalgamating tape maybe and epoxy glue between the sections. I made a film about this here: https://youtu.be/ZamtSHzzVWQ. I have been informed by James that the glue “cracked” so you may want a different adhesive.
