Excellent in class  Time owned: 0 to 3 months
I am really pleased with this antenna. I chose it over the similar Comet CWA-1000: the Diamond product has a big advantage as each band is independently adjustable by means of its own pair of tuning stubs, making set-up really easy. It is manufactured to a very high standard.

I recommend NOT making irreversible physical cuts to these stubs: instead, make “virtual cuts” by “tripling” the end of the stub backward and forward so that there are three parallel wires taped together at the end of the stub: the “seen” length of the stub will thus also be its electrical length. I heavily bandaged the balun with waterproofing tape as the screwed-on closure suggests potential rain ingress. The terminals of the coils should also be water protected. Altogether a full day’s work!

Very short of space, the 3.5/7/21 branches of my W-8010 are erected as a “W” i.e. an inverted vee with dog-legs back up to high points at the house, where I’ve fitted vine eyes through which I can pull long nylon cords to be able to quickly lower and raise the antenna for continual SWR measurement and readjustment when setting up. The apex is only 8m above ground (incidentally 2.5m below my 21/28 MHz Yagi: interaction of the two antennas is acceptably low but I wouldn’t want them any closer).

Tuned for CW, SWR is as follows. On 3.5MHz, 1.1 at my chosen resonant freq of 3520, and 1.5 at 3500 and 3540. On 7.0MHz, 1.05 at 7020, 1.15 at 7000 and 1.5 at 7070. On 14MHz, 1.6 minimum, bandwidth 200KHz between the 2.0 points. On 21MHz, 1.7 minimum, huge bandwidth. On 28MHz, huge bandwidth but couldn’t get SWR below 2.8, it resonates too high for CW, haven’t yet tried soldering extra wire to stubs.

I have enjoyed 1000km-plus night-time QSOs on 3.5MHz, implying some radiation at low angles: on this band the antenna is amazingly good for limited space. It’s also excellent on 7 and pretty good on 14, OK-ish on 21 but poor (so far) on 28. So I score it 5. Putting the 21/28 MHz issues in context, I’ve never had success on these bands with any multi-band wire antenna, and if I couldn’t have my beam for these two bands, I’d get a 21/28 vertical and keep my W-8010 for 3.5, 7 and 14.

For the price it is good  Time owned: 0 to 3 months
The antenna works ok. It needs to be at least 2 meters distant from any wall or roof. If it passes close to a wall the SWR increases too much at least in the lower bands.
Also important is it needs to be supported by good /strong mast. 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. basically I can talk to anywhere, of course much better to the directions of stronger radiation. It is ok for radiation 50 to 60 degrees to each side of the maximum, so it covers well 120 degrees (in my humble opinion).
For the price it is a good antenna. I apid more for the masts and for attaching well the masts to the wall. 2 masts are ok if the coax is not very heavy.
The ropes supplied are bad and it is better to use sailing ropes (5 mm is ok).
One important aspect is the tuning in the 80m band. 80m is the worst of the antenna because it has a very narrow bandwidth for an acceptable VSWR. 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 3560KHz.

Good antenne for little space.  Time owned: more than 12 months
Well, I have my antenne over 3 years now.
No, I am not hearing everything as I would with a towered beam. And no I don't put up a very strong signal as some HAMs that use 1,5 kW on a stacked yagi.
It's a mediocre antenna for 5 (or more bands). I make nice QSO's and I can work the world.

The fact that I homebrew it, makes no difference: it's a exact copy of the W8010.
Can I recommend it? Yes, sure.
Always looking for better antennas for my space; didn't find any yet.

Default length is way off  Time owned: 0 to 3 months
What I discovered is that at around 27 or so feet the default length of most all the 'stubs' are too long. I ended up chopping off the ones for 80 and 40 and 80 was still resonant around 3.630 which was an improvement as it was down around 3.5 Had to start shortening the 80 meter element. Was already resonant on 15 80 meters has about 50 kc of spread which isn't bad as this antenna is quite short.

However I made a giant mess of my mast's ropes and ended up with an infuriating disaster so I tore it all down and bought a comet h 422 and am happier.

Good compromise antenna  Time owned: 6 to 12 months
I bought the Diamond W8010 as my first HF antenna, intending to mount it in my attic. I used it for about 6 months sporadicaly with a tuner. I just got a new Yaesu FTDX-1200 and used an analyzer to get it right.

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. the 10m and 20m portion is run at about a 30 degree angle downwards from the top line. I also added two (app) 4 1/2 ft. wires at 90 degrees to the top wire and 30 deg. down for 6m coverage.

All bands tuned well except 80m, where I have a 900 khz section to use. 20m and 40m seem to do the best.

As I said, it is in my (one-story) attic, so it isn't a DX hunter, but I'm on the air.

Great Antenna  Time owned: 0 to 3 months
Test equipment used an Antenna Analyzer.
Setup the Diamond W8010 when I first assembled it and hung it up 4.5m high using three Jay car telescopic masts.
When I started 3.5MHz was at 3.3 MHz I wanted it to be at 3.6MHz
7.00MHz was at 6.87MHz I wanted it to be at 7.1 MHz
14MHz was at 11.6MHz I wanted it to be at 14.2 MHz
21MHz was at 20.15MHz I wanted it to be at 21.3 MHz
28MHz was at 25.8 MHz I wanted it to be at 28.5 MHz
After removing most of the adjustment stubs it became quite close to amateur band I left the 40m &10m adjustment stub as is. 20m need a lot of cutting to get to 14.2 MHz but the SWR is quite high at 1.8 other bands are all ok.
Final result
3.54 MHz 1.5
7.03 MHz at 1.4
14.155 MHz at 2.4
20.88MHz 1.00
28.5MHz 1.6
I covered all the coils with silicon tape to prevent that material from degrading in the harsh Australian sun. This just fits my backyard which is 19.6m long.
Using a SDR Play SDR I can receive local VK stations and DX stations very well I have tried 80m 40m 20m 15m and 10m with good results.

Awesome  Time owned: more than 12 months
Gave this antenna a 5 because it works very well for me at a low height of 15 feet I have changed it slightly by separating it into two dipoles by adding another balun and coax feed as I found 10m to be a little deaf but by liberating the 10m and 20m dipole away from the other its way better anyone who has one should try this it makes a big difference and is simple to tune this way all stations I work are surprised by its performance especially on 80m as its so short its crazy!!!

Small flaw  Time owned: 0 to 3 months
This is an update to my earlier review, in wich I described the dissatisfaction with the Diamond WD8010. After all it appeared that the balun supplied with the antenna, was defect. So far, things are looking good but a faulty balun out of the box should nevertheless not happen imho. The vendor replaced it with a new one in a jiffy, so good service. Hope to score some DX with this antenna!

Perfect solution for small lots !  Time owned: 0 to 3 months
I have been looking at one of these shortened dipoles for a long time. They were not available in North america until recently. In my case, it replaced also another Diamond antenna ,the WD-330 T2FD broadband folded dipole. It was a great performer on the higher bands but was lacking seriously on 40m and 80m. The W-8010 is way better on the lower bands. Assembly was pretty straightforward with the usual high quality parts from Diamond. I had to completely remove the tuning stubs to get the resonants point where i want.The bandwiths associated with a short loaded dipole with coil are pretty sharp but usable.
This particular antenna fits pretty well on my small lot with an overall lenght of just over 63'.
In my book , a good deal for the coils , quality wire , insulators , a good 1kw balun and even some rope. A+ Diamond

Does the job  Time owned: more than 12 months
Bought this aerial secondhand but unopened.

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!).

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!
