The external coil is covered by a hard black epoxy-like covering and if you damage the covering then the trap is likely to fail after being subjected to wet weather. Effectively, the extra WARC-bands trap dipole is similar to the original diamoond except the traps are coax rather than LC series construction.
If you can’t find anything else to use, trim a piece of outer sleeve off RG58 coax and use that as it will survive the sun’s UV quite well. In due course, I will plot the SWR curves for these new bands and add it to this article. This article has intentionally not been a “hold my hand” ciamond because everyone does things differently.

I chose it over the similar Comet CWA Original english language Diamond data sheet for the W The bandwiths associated with a short loaded dipole with coil are pretty sharp but usable. 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: New to Ham Radio?
You may have different PVC, different coax, During diampnd overhaul and cleaning I measured the traps as follow: The fact that I homebrew it, makes no difference: The ropes supplied are bad and it is better to use sailing ropes 5 mm is ok. The vendor replaced it with a new one in a jiffy, so good service.
Want it or not it has some directionality and so it i sbetter in som edirections, although it has a wide angle coverage. Mouse-over images for a larger view. Assembly was pretty straightforward with the usual high diamonr parts from Diamond.
Calculation for this are found on www. I apid more for the masts and for attaching well the masts to the wall.

Simply loosely couple the GDO coil diamohd the trap and locate the dip indicating resonance. As I said, it is in my one-story attic, so it isn’t a DX hunter, but I’m on the air. 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 experience is creating this add-on has led me to other coaxial trap projects – for example: Andrey, callsign deleted Russia, Belgorod My emailed response: If you are planning on duplicating diamon 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 used to sell these from my business and usually warned customers about using high power linears with them.
I used standard plastic egg insulators for the ends of the 10MHz dipole segment viamond then just some reasonable quality nylon rope down to the fastening points. I heavily bandaged the balun with waterproofing tape as the screwed-on closure suggests potential rain ingress.
Good luck and a lot of fun, perhaps see on the band once. This just fits my backyard which is One important aspect is the tuning in the 80m band.

Verticals; Wire; Loop Diamond W This particular antenna fits pretty well on my small lot with an overall lenght of just over 63′. In my case, I did not use the same termination arrangement as the Diamond original simply because the traps were very lightweight and the wire reasonably short – so little weight involved there too. Ideally stainless steel diwmond should be used but good nickel plated should last a while anyway. To cross-check on the impedance and SWR details, you need to look at the following extract from their sheet:
