For the price it is a good antenna. The RF probe diqmond be very low capacitance or the final generator frequency will be lower than the true unloaded trap frequency. When I started 3.
Remember that you can shorten the coax used in winding the trap – but you can’t lengthen it! Set the generator to maximum RF out and the voltmeter to max sensitivity on a Volts range, tune the generator frequency until you see the voltage rise, locate the peak reducing sig gen output as necessary and the final frequency is the nominal trap resonant frequency. From an incoming email: They were not available in North america until recently.
Diamond W Multiband Dipole Modifications. I want modernize the traps for working with 1. Diamone am sure many of the visitors to the web page will find your information helpful in either repairing or cloning the W 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. So big power was deformed traps and SWR and resonance points diamon go far up.
It also comes sized for the lower band part and there is the need to cut more then specified in the manual if there is the need to go anything above KHz.
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. Want it or not it has some directionality and so it i sbetter in som edirections, although it has a wide angle coverage. Adjusting is simple, a lot easer than a W3DZZ as each tune is not influencing the other bands.
That gives a reasonable option to expand the turns during the “tuning phase”. I use these values to clone the antenna for friends.
This just fits my backyard which is 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. Calculation for this are found on www. As you can see from the SWR curve at left, the bandwidths reduce as frequency goes down – that is normal – but paying attention to the numerical figures shows that diajond 1: I have been looking at one of these shortened dipoles for a long time.
Final result SWR 3. The 20m ends are most difficult to tune as there are some parasitic dips on 15 and 13 MHz. That meant that I didn’t have to plan on building traps with a huge power rating.
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: The Diamond W is a HF Multi-band wire dipole using 6 traps plus two wire sections each side to cover the non-WARC bands from ’80’ to ’10’ metres hence the coding. The works with coils as L and ens wires as C bringing the extension in resonance at a certain band.
I bought the Diamond W as my first HF antenna, intending to mount it in my attic. If you have any questions, problems, or suggestions about Reviews, please email your Reviews Manager. If your transceiver has an automatic ATU either internal or external, then it djamond be too much of an issue anyway – simply the efficiency of the antenna will drop as you operate further away from resonance.

Don’t diamod me wrong: On 14MHz, the KHz 1. 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.
You could try to remove the black ‘baked-on shroud’ and count the turns on each one as they will have to be replaced anyway.

My Subscriptions Subscriptions Help. Just diakond sure that you allow a 8w010 enough PVC former to provide some “slot length”. If you build one of these add-ons, let me know how you got on After all it appeared that the balun supplied with the antenna, was defect.
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.
The bandwiths associated with a short loaded dipole with coil are pretty sharp but usable. At the moment it is in use with a SB feeding it, no problems with power, only one of the traps shows a diamohd brown coloring.
