My Last Antenna Time Owned: more than 12 months.
N4LQ says it best and says it all in these reviews. Since that was written some adjustments were made for heat and moisture venting and warnings of running too much power on digital. There are also numerous improvements across the entire product line. In 32 years at this QTH and many antennas on my smaller lot, this is the best of the best for hearing and working them while not being clobbered with constant irritating noise. Yes, I also use one of the CMC filters offered. Great antennas and why Danny has a big job getting the orders out the door.

Outstanding Design, Construction and Performance Time Owned: 0 to 3 months.
I sought a wire antenna to supplement my 24 foot vertical (which wouldn't load on 80M). The design and construction of this antenna is simply top-notch. Professional in appearance and performance. Without a tuner, had SWRs less that 1.34:1 across all bands (except 17m where it was 1.85:1). With my LDG AT200Pro II added, I got the following:

1.840 Mhz SWR: 1.39:1
3.573 Mhz SWR: 1.45:1
7.047 Mhz SWR: 1.21:1
10.136 Mhz SWR: 1.31:1
14.074 Mhz SWR: 1:1
18.100 Mhz SWR: 1.9:1
21.074 Mhz SWR: 1:1
24.915 Mhz SWR: 1:1
28.074 Mhz SWR: 1:1

I couldn't be happier with its performance.

Brilliant Time Owned: 6 to 12 months.
Like many I was eagerly anticipating 3Y0J...then my hexbeam balun failed. With no time and poor weather for a repair, my "emergency" EFHW went up at about 25 or 30'.
I already have 2500+ band-slots confirmed, so new ones are tough to come by. Nevertheless in early 2023 I've already picked up a ton of new band-slots: 8Q, 4S (2 bands), OH0, 3W on 80m, 9U (5 bands incl. 80m), EP (2 bands), D2 on 80m, FT8w (3 bands), YJ (2 bands), 3A, JY on 80m, 9N on 10m, EX, EY, ZC4, VK9C, and 3B7 (6 bands incl. 80m)...and yes, one precious contact with 3Y0J for #338.
I could probably have picked up another slot with FT8W or 3Y0J with the hex...but I certainly don't have to rush out in bad WX to fix it just yet.

On FT8 I run it at 750W and I haven't overheated the cores once (I used to have the 1K version and on the low bands, 500W would overheat it after maybe 6-7 minutes of continuous activity). Otherwise it's full boat out of my KPA1500 (the built-in tuner really plays well with this antenna!).

THANK YOU DANNY

My best antenna so farn ICOM 7300 Time Owned: more than 12 months.
I installed this antenna three years ago. I had to run it from my shack to a tree and then 90 degrees to another tree. It is mostly about 35 feet high. I drive it with an ICOM 7300 running SSB and digital. It has helped me achieve DXCC and is my main antenna.

Careful on the Power Time Owned: 3 to 6 months.
MyAntennas has done their best to provide an all-band antenna that works at high power.. but there are limits.

Those cores.. either three FT 240-43's or a mix of FT 240 43 and 52 cores.. they may saturate then start to heat up at a certain sustained power level. Then they start to change characteristics. Then the SWR goes up and things get worse. Even at peak SSB power levels those cores may start to saturate at some point.

That's why they say 350 watts for FT8 or any key down mode like FM on 10. The core efficiency may be anywhere from 80% to 95% depending on the band and situation...but pushing 1.5kw @ 80% worst case efficiency? Things are gonna warm up in that little box.. Be careful with really high power.

It would be interesting to do a 1 min test at high power or at various power levels and at various frequencies, then check the core temperature changes with one of those point and shoot temperature gauges similar to what they use for COVID. If the core doesn't warm up, then the RF energy transfer via the transformer from 50 ohms to 2500 ohms is really efficient.. They wind their transformer 56:1 which may give a better ratio to the actual Z the antenna presents. Then there is the wire gauge they wind the cores with... ya know there are some serious current points in that wire down around the 50 ohm input. There skinny wire doesn't cut it @ 1.5kw because of the potential I/R losses.

Making EFHW antennas work is a kind of black art voodo... but hey, that's what ham radio is all about.

Outstanding!! Time Owned: 6 to 12 months.
This EFHW is the best wire antenna that I have ever used in over 30 years in the hobby. My configuration has the transformer mounted 30 feet on a pole, and the wire in an L configuration. My antenna analyzer shows an swr of 1.8:1 or better on all of the bands. I am so impressed with its performance I have a 2nd 80-10 in the box for a backup and/or field day. Money well spent! AAA+++

Excellent Time Owned: more than 12 months.
Low SWR on the bands with about 2 to 1 SWR on 75 meters. It does not hear as well as some other antennas, but 20 foot installed height may have contributed to the less than stellar receive performance. Overall, a great antenna.

Great antenna Time Owned: 3 to 6 months.
I've had this antenna up for about 3 or so months and I have to say, I am impressed. This is my first EFHW antenna. I have in in an inverted L, vertical goes up 30 feet and the rest sloping down to around 15 feet. Great ears, low noise floor. In this configuration it's good for regional comms but I have been able to reach down into S. America a couple of times. All in all, I give it 5 stars.

A Real Winner! (update for HP Version) Time Owned: more than 12 months.
Best antenna money I’ve ever spent. Low SWR across ALL the hf ham bands ( note that the 40 meter version only covers 40-20-15-10). Extremely rugged and has held up well through winter storms and summer heat. Made of extremely high quality components and strong no-stretch wire, it should last for many more years to come. I’ve been VERY pleased with the performance and quality of this antenna. Highly recommend

Update 02/10/2022 -- with the addition of an Acom amp, I bought the Hi Power MyAntennas 75-10 version. The amp provides just a little too much power for the lower power version and the core heats up and the SWR rises - not so with the HF version! Even with the slight cost increase, these are still a great bargain and are stellar performers, with low SWR right out of the box. . I took down my 43 ft vertical and now rely on this great EF antenna for my 75-40-30 meter work. In 50 years as a continuously operating ham, this is by far the best investment I've ever made in a ham antenna.

Great end fed Time Owned: 3 to 6 months.
I was skeptical about this antenna. I am pleasantly surprised. I have the antenna set up in a sloping configuration. The high point is about 65ft sloping down to 10ft at the Feed point. I have one ground rod. The antenna tunes great on most bands. I read in this thread that someone was using 900w on FT8? The manufacturer clearly states 350w continuous duty. I run 350w on FT8 all day long and 600w on SSB. The transformer operates at normal temps. I have made 1000's of contacts. My "main" antenna was a 205' g5rv at 65' flat topped. The EFHW-8010-2K preforms much better then the G5RV. It hears better too!
