I apid more for the masts and for attaching well the masts to the wall.

I make nice QSO’s and I can work the world. Added 24 Octfrom an incoming email: Adjusting is simple, a lot easer than a W3DZZ as each tune is not influencing the other bands. I don’t really plan to operate much on these WARC bands 12 metres, 17 metres and 30 metres but that old proverbial Murphy has it that if I don’t prepare for it then sometime real soon, I will need to – and then it will be in a hurry.

It sounds like you could have had the insulation on the enamelled wire break down and you now have diamnd turns on the faulty traps.

Want it or not it has some directionality and so it i sbetter in som edirections, although it has a wide angle coverage. I am not going to tabulate the exact trap details here because you will probably have different coax, or a different PVC former, and you can just as easily work out your own using the software, but the general format was calculated as follows: One important aspect is the tuning in the 80m band.

Diamond’s power rating of 1. Take care that the insulation on the wire cannot be damaged or the tuned length will vary as it makes contact then open-circuits again with swaying in the wind. Ideally stainless steel hardware should be used but good nickel plated should last a while anyway.

I’m the guy on the photo with the white shirt Can I recommend it? Here’s another hint for success: The start hole is fine – just the “end hole” idea needs to be modified. No, I am not hearing everything as I would with a towered beam.

I live in a high wind area and the antenna is on top of a building so I used 2,5 inch OD masts with 4mm wall thickness. In due course, I will plot the SWR curves for these new bands and add it to this article.

One tuning method gives slightly more “gain” than the other. The bandwiths associated with a short loaded dipole with coil are pretty sharp but usable.

Other designs see the wire lengths between the traps shortened to fine-tune, which in itself is a very messy and time consuming process. 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.

Just an addendum of interest regarding the Diamond W – a warning if you want to take it that way Note that the nylon rope supplied seems to be a marine-grade version and should last for many years. I have been looking at one of these shortened dipoles for a long time.

The top 15m, 40m and 80m wire is mounted along the ridgeline of my attic, and i had to bend the ends of the 80m wire 90 degrees to fit. I ended up chopping off the ones for 80 diamod 40 and 80 was still resonant around 3.

It was a great performer on the higher bands but was lacking seriously on 40m and 80m. Mine is hanging only 4m high and I can work the world, contest with nice scores and have great fun.

I heavily bandaged the balun with waterproofing tape as the screwed-on closure suggests potential rain ingress. To djamond on the impedance and SWR details, you need to look at the following extract from their sheet: I recommend NOT making irreversible physical cuts to these stubs: That would have meant another 3 wires out each side and even though they don’t need much separation and can be fabricated such that the higher bands ‘droop’ from the lowest band, they are a bit of a problem to tune.

Everyone will have a different method of terminating the trap – wire loops through the ends, screw terminals like mineI use and cloned this dipole already for over 15 years, with great enthusiasm. Most importantly, adjust Dismond sides of the dipoles similtaneously, whether it be a tail-cut or a wind-back.

Building and tuning was simple enough – although I did make it a bit little shorter for 80m that I would have liked no tuning stub for 80 either! If you are planning on duplicating the likes of a W then you need to pay attention to the lengths between the traps and take heed of how they originally set up the trap terminations: I chose it over the similar Comet CWA This is an update to my earlier review, in wich I described the dissatisfaction with the Diamond WD My Subscriptions Subscriptions Help.

One of the ideas that they did use in this design as against other manufacturers’ designs seem on the web was the use of tuning diamonx.
