Don’t understand negative reviews - mine just works  Time owned: more than 12 months
I am using my second Butternut, having given away the one I bought in the 1980s to a ham down on his luck when I had bought a home with a 50’ tower. Then I had a luck downturn, and ended up buying a used one in 2008 on Craig’s List after giving up on an inferior Cushcraft R7.

Living in a rented little suburban cape in 2008, I didn’t want to bury radials, and so I mounted it on a 5’ Radio Shack length of TV mast driven into the ground, and used the same twin-lead radials shown in my saved 1980s literature. The radials were just 4 feet above the ground, so it was going to be a pain to mow under. But wasn’t sure it would work well at all.

It worked GREAT! I followed the directions for assembly exactly, and my MFJ antenna analyzer showed it was really close except on 80 CW. I guyed it in the middle of the coil section with “parachute” cord, anticipating tough north-of-Boston winters.

Fast forward 11 years through multiple savage winters (including the 6’ snow of 2015) to May 2019, that old Butternut and 11-year-old radials are still working great, except the 15 meter stub is broken. I took it down, cleaned the joints and installed new bolts, replaced the broken 15 meter stub, and re-erected it with a 6’ length of saved Radio Shack TV mast from 11 years earlier (devised a kind of tilt-over with the old 4-foot mast and stainless hose clamps) Couldn’t find a twin-lead source so I cleaned the ends of the old radials and reinstalled them, and a single 67’ copper wire radial for 80 CW.

The 2019 June/July weather is hot, so I ran the coax to my air conditioned office, and attached my Elecraft KX3 - 15 watts CW. And darned if it doesn’t make contact after contact all over Europe and South America. Just for kicks, I decide to check into ECARS on 7255 SSB - I rarely try SSB with the KX3 - and get a surprising S9 report.

When the weather cools, I will move the coax and KX3 to my “sunroom” shack where my TS940S feeds 40 and 80 meter common-feedline antenna up 20 feet for high-angle short-range communication (the Butternut isn’t very good for under 400 miles - too low radiation angle

Now, band conditions in 2019 aren’t anything like they were in 2008. They truly suck. Forget about 80 meter DX like back then, but 40 still has flashes of life, and 30/20 still live.

I find this a very credible antenna. At today’s $600 price, it would take an act of faith to pick it over a cheaper antenna. And I am sure those who decry its need for antenna analyzers and other complaints have their own experience. I’ve just found my two Butternuts - one roof mounted in the 1980s, and mine ground mounted up 4-6 feet with in-air radials - really works. Works well. But then again, I work 99% CW. Your results may vary.

Still working well after 20 years  Time owned: more than 12 months
I purchased this antenna long time ago. She survived two moves. It is an antenna that must be reinforced in the middle. I added three aluminum "L" to stabilized the junction and since then it has held up well in storms. The antenna is difficult to adjust but once done, it works on all bands. Even on 80m, I can use it on the whole band with a tuner.

The antenna is mounted on the ground and requires multiple radials cables of different lengths. I buried them under the grass.

Additional Data  Time owned: 3 to 6 months
I purchased this Antenna from DX Engineering, the phone help was outstanding.
I assembled the antenna using their recommended Copper paste, the recommended radial plate, 20 omni directional counterpoise / ground radials with landscaping hoops to hold the wires down.
The grass has overgrown the wires and are not noticeable anymore.
Please read the instructions, they are well written, but you can get overwhelmed during the tuning process.
Do tune with an antenna analyzer, no room for guessing here.
I have made recent contacts to Southern Argentina, on 10 meters.
Not bad for a ground mounted vertical.
Now that the weather is warming up, I am going to re tune the antenna and pick up those other bands that I did not initially tune for as I just got my General License.
Again, I really like this piece of equipment.

I am totally Impressed  Time owned: 3 to 6 months
I got licensed in October 2015,and went through the gambit of antenna shopping, for verticals. In my location, I have to be sensitive for home owners association issues. You Know the drill. I listened to the rants about counterpoise versus no counterpoise.
There are a number of fine vertical antenna manufacturers out there, and I looked at them all. Honestly !
I wanted a simple(not here), inexpensive(not so much),and a well performing antenna system.
When I buy something I try to buy the best for the current need and for the near future.
I honestly did not want to spend the money, however, I ordered the Butternut, and downloaded the manual for study.

When it arrived, I studied the instructions "AGAIN", then followed the instructions and the recommendations for building and installing this unit.
Finished unit pictures can be seen on my QRZ page. Due to the weather, and my license at the time, I did not tune all the bands, rather just the ones that I knew I was going to use right away.
I have 20 thirty three foot counterpoise radials, just under the grass, the only part besides tuning that I did not like..

Use an antenna analyzer on this antenna for set - up. If not then don't buy this antenna, you will do you and your equipment a major disservice.

Since I have been on the air, I have learned that there are a bunch of these out there, if not in use, torn down and stored, people are just not getting rid of these antennas when they move on from it.

The performance of this antenna outstanding! I always get complements on my signal for the power that I am running all the time.
I am impressed with each and every long distance contact the I make. I am in the phone bands primarily, and that is what I am tuned for.

I am running a Yeasu FT-991 usually with the power turned way down.

It's not a beam, for sure.
If I had it to do all over again, I don't believe that I would do it any differently!
I like this antenna system, Again the performance is just outstanding.

DXE- Butternut  Time owned: 3 to 6 months
DX Engineering recently acquired the brand. I included with the antenna their DXE brand radial plate/W their UHF coaxial splice connector mounted to the Plate body,DXE Radials(60),Jet lube SS-30 assembly paste, and their pre assembled 100ft DXE 400MAX w/their newly patented UHF silver connectors.
The performance of this classic multi band vertical antenna with the combined DXE RF Radial system is excellent...The contacts are excellent! I also included a Balun Designs Max choke model 1115DU at the antenna feed point.

Still My Pick  Time owned: more than 12 months
I've had three HF6/9V's over the last 30 years. Just ground mounted the third one since I've moved to a new short-term QTH and can't put up the tower/tribander.

I still think this is one heckuva vertical antenna. Just played in the CQWW CW contest on 10 meters and worked 105 DXCC entities in eight hours of operating (with 500 watts.) That's pretty darn good! On the other end of the spectrum, it works surprisingly well on 80 meters also (acknowledging it's rather limited bandwidth) as evidenced by logging FT4TA and needing only about 15 minutes to do so.

However, know that a good radial system is very much a part of the recipe. I use fifty, fifty foot radials.

Highly recommended.....

Mike, NE8P

Great All band Vertical  Time owned: more than 12 months
MY dad owned two - one permanently mounted, one just for Field Day

I have had mine for 6 years.

I am in an antenna restricted neighborhood, so I have the HF9V behind a palm tree on my property.

This thing works and works and works.

I have DXCC on 6 bands and WAS on 7 bands using this antenna exclusively.

It may seem a bit more expensive than others, but this antenna really works, I can not recommend it enough

good but manual and comenents need more anttention  Time owned: 0 to 3 months
cheap replacement caps found here if you break one higher kv that original here my results now if bencher had made it more durable better assemble had redo the q coil connectors badly soldered , the rg 11 also badly soldered pl259 as well as the soldier crimps, use copper its a better quality of cable than steel caps weak but now got the antenna tuned within acceptable limits. If the manual and above had been done properly I would have given it a 5. but tuning needs analyser and a lot of patience. 6m will be raised a little at some point but its acceptable for now. Be careful on 30m coil the cap is very brittle. Here is my new results. Im a lot happier now with it:-

54.000 3.5 I have not finished tuning yet will have another go tomorrow will raise 6m a it and try and get 20m down any tips
in uk we do not have the 7.2-7.3 MHz part of band.
due to the amount of tuning and not completely understandable instructions (a lot hazy in places ) I had to repair this several times as I have retuned(fine tuned) it now about 150 times . sometimes this ahs thrown the antenna out a lot , I have my manual tuner in bypass mode for tis antenna so these are native figures, I used mfj269pro for taking he readings . any help for getting 20m and 17m down lower would be greatly appreciated as I would like tom use my ft857d on this antenna as well as "my boat anchor" the ts530s which I a brilliant radio , reason being putting a switch in to switch between radios some relay system, and the 857d don't like swr being greater than 1.5:1 as a rule where the ts530s handles that with ease
The radials are buried.
the resulst are a cut and paste form the xls spreadsheet made by ac8de but with my results in.(avail in the yahoo group) .
oen tip for you guys I have found don't always move the mount sometimes just adjust the coils for fine tuning(ie stretch of compress a little). movie the up or lower swings the swr to much
