Don’t get me wrong: The bandwiths associated with a short loaded dipole with coil are pretty sharp but usable.
All bands tuned well except 80m, where I have a khz section to use. Diamond’s power rating of 1. I heavily bandaged the balun with waterproofing tape as the screwed-on closure suggests potential rain ingress. Works well enough – although it’s nothing I couldn’t have built, it was good value with a proper balun and the weather at my parent’s QTH means that most homemade aerials don’t last long! I have taken a quick copy of the translated page and put it on my web site to make it easier for those of us who do not read the Dutch language.
Mouse-over images for a larger view This is the basic layout of the W, 3 traps on either side of a balun supplied.
Final result SWR 3. That meant that I didn’t have to plan on building traps with a huge power rating.
The ropes supplied are bad and it dimond better to use sailing ropes 5 mm is ok. I had to completely remove the tuning stubs to get the resonants point where i want. This just fits my backyard which is At the moment it is in use with a SB feeding it, no problems with power, only one of the traps shows a little brown coloring. During a overhaul and cleaning I measured the traps as follow: Dizmond, callsign deleted Russia, Belgorod.
The very ends of the dipole legs terminate on plastic insulators and to provide for the adjustment tails, the wire length is effectively somehat shorter due to the initial 55cm fold-back, some of which is used for the knot.

I have enjoyed km-plus night-time QSOs on 3. As I had a reasonable supply of Belden RG miniature coax on hand, I created some traps using that cable. The interaction between the elements because of the close coupling means that adjustment of one dipole in the ray causes de-tuning in another – so around the loop you go – yet again! On 20 and 80 metres, it is the tail at the end of the dipole legs.

Trap dipole for WARC bands. What must diiamond is that the traps for each side be tuned to the same frequency! This article has intentionally not been a “hold my hand” style because everyone does things differently. You need to expand the turns i.
Only the ends are a little sensitive the height and moisture. Balun to 24MHz trap length P: My construction notes are only in Dutch This particular antenna fits pretty well on my small lot with an overall lenght of just over 63′.

I used standard plastic egg insulators for the ends of the 10MHz dipole segment and then just some reasonable quality nylon rope down to the fastening points. Just a tip – don’t cut the tail on the 10 MHz element wire length R – wind the piece below the termination insulator back along itself a section at a time and recheck the centre frequency.
The start hole is fine – just the “end hole” idea needs to be modified. This works perfect on high power as the high voltage is only at the end of a adjustment element. The W is way better on the lower bands. Everyone will have a different method of terminating the trap – wire loops through diamon ends, screw terminals like mineSelf-amalgamating rubber tape would be even better – the stuff you should use on all of your exterior coaxial connection joints instead of plain old insulation tape – as it won’t ever come apart, even when exposed to some pretty horrid weather.
For those who ddiamond familiar with it, the Diamond BU balun is just a 50 ohm 1: No, I am not hearing everything as I would with a towered beam. My first traps were all high in frequency according to my GDO relatively accurate so that meant that I had to allow more coax initially.
I want modernize the traps for working with 1. That gives a reasonable option to expand the turns during the “tuning phase”. Together with a friend of my, PA2Gwe build this antenna and published the experiment in our league magazine, a summary of this you can find on http: The solution was to create an extra trap dipole for the 10, 18 and 24 MHz bands – surely that can’t be too hard Note that the nylon rope supplied seems to be a marine-grade version and should last for many years.
I make nice QSO’s and I can work the world. As this was built as an “add-on”, the extra wire elements of the new dipole were simply added “in parallel” to the existing dipoles at the balun.
