| Excellent performance and quality |
Time Owned: 0 to 3 months. |
A winner!
End-Fed after one month usage: outstanding performance US and Europe, high quality components, and easy installation. Rated at 1k. Unlimited Antenna configurations (inverted L, Inverted V, Sloper) based on your skyhooks and radiation pattern desired. Good receive ...monitoring a YC2 from Indonesia at 1700hrs local time on 7155 ssb while composing this review. Loads beautifully with my Flex 6500 and AL80A and no rf issues in the shack. Behaves as a
collinear on 40m.
This is not a compromise antenna and has become one of my two main antennas, the other being a full wave 40 meter loop in a vertical configuration. Just ordered a 2nd end-fed for an alternate configuration setup.
Had a question today and spoke to Danny who is a gentleman with a wealth of knowledge, and open to any question.

I chose this antenna largely based on installation requirements at my QTH and user reviews. The current installation has the antenna fed with 100' of RG-213 with the feed point at about 6 feet high. The wire runs essentially south for 65' to about 25' high then runs east for 65' with the end also at 25'. With the current band conditions being rather bad I have run mainly digital modes to date, mostly JT65 and PSK31 on 80, 40 and 20 meters. SWR is a bit high on the low end of 80 meters but tunes up easily and produces coast to coast coverage from central NM. SWR on the higher bands is very good and performance is excellent. I have not attempted to trim the wire yet since my installation will change in the near future - any trimming will be deferred until then!
Design and build are very good. I see no reason why it will not hold up for years to come. There is, of course, no magic, does everything, one size fits all antenna - the laws of physics apply!
That said, this antenna seems function quite well within those constraints and I do not hesitate to recommend giving it a shot. |

| Stealth endfed with great performance |
Time Owned: 0 to 3 months. |
| In a topic about endfed halfwave antennas in a dutch forum, I was informed about myantennas.com and ordered EFHW-8010 from Danny. It came prompt and well packaged to my home. As a resonant antenna on many bands it is receiving very well, better than my random length longwire. On the 5 classic DXCC bands and 12M it has a SWR around 1:1.5 and doesn't need any tuner. For 17m and 30m internal rig tuner quickly get a match. The matchbox is sealed and time will tell, if it will survive harsh winter months. Overall I am very happy with its performance. |

| Real end fed multi band |
Time Owned: 0 to 3 months. |
| Found a nice neighbor that Let me use his tree, Far end is only at 25' and at the house only 18' but it is true multi band. I can work 80 to 10 without a tuner and worse case is SWR 2.1 and getting good reports. On JT-65 I get about same report as I send so I am getting a good signal out. |

EFHW was used by OH2BH on all bands from ZA1KS with 1 kW SSPA without problems! OH2YY used Cushcraft R5 halfwave vertical without top trap on 10 and 15 m bands. Dipoles for 40 and 80 m on the second site.

| Excellent antenna !!!! |
Time Owned: 0 to 3 months. |
I saw the advert in QST a few weeks ago, and decided to buy one, to use as a general purpose antenna for an upcoming DX-Pedition to Mozambique as C91J and C91B next month. It will be used as a spotter antenna for a 2 element SteppIR beam, and to use on 80/40, in conjunction with some verticals.
The service I received from Danny was top notch, he is very quick to respond to emails, and very obliging to any requests I have made. I had the EFHW 80-10 sent out to Wales, UK where I am on vacation. I installed it with the feed point at 15 ft sloping up to a tree at 50 ft, and I grounded it to bleed off any static. I then swept the bands with a graphic antenna analyser. I am very impressed with the results !!! it performs just as it was advertised. Low SWR on all the bands, and no ATU required !!! I had great trust in Danny's abilities, knowing he had worked with Cushcraft as an engineer for many years on their HF vertical antennas that don't require radials - half wave design.
Danny has performed some magic with this antenna. Of course it is not a beam, but for a simple end fed wire it is very impressive. I have installed it here in Wales and have been comparing it to a Gap TITAN vertical, a 40 m loop, an 80 m loop and an 80 meter 1/4 wave vertical with 60 ground radials. For DX, on the bands 40 - 10 the EFHW beats the antennas mentioned about 95 % of the time. On 80 meters the 1/4 wave vertical with 60 radials beats the EFHW usually by about 3 db, or half an S point for stations further than 3000 miles away.
For anyone thinking of putting up an all band wire antenna, I have no hesitation in recommending this antenna. If you think of the alternatives - G5RV, Windom, Carolina Windom, ZS6BKW etc etc, well this antenna has the distinct advantage of not requiring an ATU, is easier to install - the feed point need not be high above the ground, and it performs slightly better in tests I have done. The other advantage, is because the SWR is low at the feed point, the losses in the feed line will be far less than other all-band antennas that require an ATU, meaning more ERP. |

| Excellent antenna, especially for limited space! |
Time Owned: 0 to 3 months. |
| I needed an effective low-band antenna that I could put up and keep the wife happy too. I wanted to string it partially between my two chimneys (about 40 ft) and stretch the rest of it into a tree in the far end of my back yard. Feeding it like a normal flattop involved coax and unsightly center insulator being visible. Danny, owner of My Antennas, a former antenna designer at Cush-Craft, suggested an end-fed design, the EFHW-8010 for this configuration. I always felt end-fed antennas had low angle radiation, but at lower heights (3 ft off my roof for part of it), it would have a lot of high angle radiation. Sure enough, it works like Gang Busters! SWR is 1.5:1 right where I use it most on 80 meters (after some trimming). The antenna works great and is hardly visible with #18 black wire. If you have a unique installation or just want a great antenna, check out Danny's web site, www.myantennas.com. You will be very pleasantly surprised, and it handles the power too! |

| Nice multiband end fed antenna with low SWR |
Time Owned: 0 to 3 months. |
I spotted this antenna online, and being a fan of end fed antennas I decided to give it a try. I've got 40m and 80m dipoles at my QTH, and combining them in a single antenna was appealing. Also, I use an ALS-600 no-tune amp and having an antenna with low SWR on multiple bands makes operation convenient. The EFHW-8010 easily handles the 600W power output of my amp. Plus, the EFHW-8010 can serve as a backup antenna for my hex beam on the higher frequency bands.
The antenna matchbox is installed at the top of a 17' PVC mast. The antenna wire is supported at the midpoint by a 32' fiberglass mast, and the end is tied off to a tree at 35'. I've got the matchbox grounded, and have installed a common mode choke at the feedpoint (which is possibly overkill).
I checked SWR with my analyzer and on most bands it is excellent. The minumum SWR is less than 1.5 on the 10, 12, 15, 20 and 40 meter bands. Across the 12, 15 and 20m bands the SWR is less than 1.6. For 40m it's 2.0 or less from 7.0 to 7.3 Mhz. On 80m, the minimum SWR is 1.6, and it is below 2.0 from the bottom of the band through 3.7 Mhz. The antenna doesn't do quite as well on 17m and 30m (the harmonic relationship of these bands is a bit off) and SWR is 2.3 and 2.8 respectively.
But SWR aside, how the antenna performs is the important point. I've done comparisons to my 40m and 80m dipoles as well as my 6BTV multiband vertical and the performance is very similar. On some occasions the EFHW-8010 is a little better, and sometimes it's not - but it's close. So I can say the EFHW-8010 works very well.
All in all, I'm very satisfied with the antenna. It works well, it's multi-band, it complements my other antennas and is relatively easy to install since it's end-fed. |

| Works as advertised |
Time Owned: 0 to 3 months. |
| The only "problem" I had was setting it up in the space I had. Getting it at 20ft at the 65ft point just didn't work when angles had to be 90% or more. Mine is more a weird "L" with a 20ft rise at about 50ft, dropping to 10ft at the lowest point. The antenna worked even though my install was a little unorthodox. I am in Colorado and routinely talk to station in PA, MD, NC and VA. I have NO COMPLAINTS!! With my internal tuner the worst case I have is 1.7:1. |
