Excellent Stealth Choice Time Owned: 3 to 6 months.
Like many of the other DXEE reviewers I require a "stealth" antenna due to neighborhood covenants. I considered both homebrew and commercial antennas and finally chose the DXEE as the simplest solution to obtaining multi-band capabilities from an attic mount. It's been an excellent choice. The DXEE is very well constructed and simple to assemble. I contacted Alpha Delta with a question regarding tuning and had an answer within about an hour. I consider that excellent customer service.

Performance is excellent given the mounting limitations (about 20-25' mounting height, 1-2' from wood structural elements, "almost" a flat-top, "almost" 180 degrees, etc.). I can't work everyone I hear, but I can work many of them at 100 watts.

A WORD OF WARNING: The design of this antenna (Hi-Q) can give you as much as a 6-8x change in SWR from the bottom of the 40M band to the top in an attic mount. It's crucial that you use an analyzer or SWR meter to help you get the antenna length correct for your preferred portion of the band. Once you do that you will still require an external antenna tuner to maximize your 40M band width and to lower the SWR on other bands.

Works Great with FT-990 Time Owned: more than 12 months.
Installed the DX-EE between two trees in the backyard at 20 feet. The antenna tunes fine using the internal tuner in the Yaesu FT-990 on all the low bands including WARC. Without the tuner I am limited to 10, 15, 20 and 40 meters. The SWR is a little high on 40m (w/o tuner)and the bandwidth a bit narrow which is to be expected. It's very well made too!

Great antenna Time Owned: more than 12 months.
I have my antenna mounted in the attic due to antenna restrictions but it has performed better than my Hygain DX88 and ZeroFive verticals. You can't beat the cost and if you need a antenna hidden in your attic this is the one.

Great Attic Solution Time Owned: more than 12 months.
I have one installed in my attic. I've tried about a dozen other antennas up there (G5RV jr, etc.) and nothing came close to the performance experienced with this. Yes, as others have said, 40 is a bit tight, but that should be expected, based upon it's length.

Hundreds of QSO's at this point with it running 100 watts or less, with good reports. I have it mounted approx. 21 feet up in a flat-top configuration.

If you need a nicely built antenna for an attic situation, look no further. This is the one that you want.

Very nice antenna Time Owned: 3 to 6 months.
This antenna is built like a tank. Very nice, high quality item. Performs very well on all bands, and yes....it is narrow on 40 meters. BUT....that's what the manufacturer states in the product description and instruction sheet! Hello....the coils are for, you guessed it, the 40 meter band to shorten the overall length of the antenna. Shorten it, add some coils....2:1 SWR bandwidth will decrease. Even the people at Alpha Delta can't do anything about the laws of physics.

Great, high quality product. Couldn't be more pleased with this antenna.

Ok Antenna Time Owned: more than 12 months.
I have owned and used the DX-EE for several years. Not the antenna I wanted but it fits btwn the 2 powerlines crossing my yard, One end up about 35' the other at 12'. It works good and using my IC-736 I can tune up 40 cw thru 6 meters with it, except for 40 meter Phone or 17 meters(that's why the 4 instead of 5). With those I have an external tuner that does a good job. I would recommend it for someone with limited space to put an antenna.

Follow-Up re: Attic Installation Time Owned: more than 12 months.
This is a follow-up message regarding my Alpha Delta DX-EE that I installed in my attic.

The antenna is still working at peak performance. I have completed my WAS on 20 meters with the antenna in my attic and 100 watts. I'm also more than half way completed with my contacts (50+) towards my DXCC.

From September 2007:

If you are looking for an attic antenna and you are interested in working DX, you'll want to take a look at the Alpha Delta DX-EE.

The antenna was easy to install....no tuning or adjustments...and the results are amazing !!!!

Although I don't have a lot of time to devote to the hobby, I've already logged over 200 QSO's in 27 countries using less than 100 watts.

It's hard to believe that I can string up a DX-EE antenna in my attic in Southeast Michigan and have a QSO with someone in Russia or Poland.

Alpha Delta DX-EE Time Owned: 0 to 3 months.
Put up the antenna today. It is in an inverted "V" configuration with the apex at 25'. I've got a Diamond A-50X on top of the 10 ft. TV tower bolted to the side of the garage. The unit was built as per the AD instructions with no attempt to tune, and fitted to be tight to support the mast. SWR is in the 2.5 to 3.0 range for 20M and 40M, and below 2.0 for the other freq's. I had always intended to put an LDG-AT200 in line with the antenna, so the SWR is OK. The antenna is much louder than my vertical, so I must have done something right. No complaints. a robust, and heavily constructed antenna.

Better than I ever expected Time Owned: 3 to 6 months.
Having used the DX-EE for a few months now I thought I would update my previous report on the DX-EE mounted in the roof space of my house.

I am now using a Yaesu FT-450AT and the DX-EE tuned up OK on 20-15-10 with the internal ATU. However, I had to trim a few inches off the DX-EE to get it to resonance on the phone portion of the 40m band.

From my home QTH in South Wales, UK, I have had recent SSB 20M contacts in Asiatic Russia, Madagascar, South Africa, Los Angeles (5300 miles) and Sao Paulo, Brazil (5800 miles)

Many contacts have large Yagi antennae and they are consistently surprised when I say that I have a dipole in the roof space.

I was happy before; now I am even more so.

Very satisfied Time Owned: 0 to 3 months.
Purchased the DX-EE a day before IARU contest as a back up antenna for 40 meters. My Cushcraft A4S 40 meter hats had fallen off and didn't get the parts in time to fix it for the contest. It took me all of 2 1/2 hours to assemble and about another hour to put up. I used a 20 foot aluminum pipe mounted in a vent pipe on my roof. I shortned the ends for 40, did not cut just pulled thru per the instructions for ssb operation. Testing the antenna on 20, my first contact was with a ZL station. Curious to see the difference I switched to my A4s during our qso and was given a report 2 s-units less than the DX-EE. Of course you never know with band conditions but very happy with the performance. I ended making about 60 contacts on 40 mostly US stations but I did make contacts with stations in Hawaii, Brazil and Morocco! Don Tyrell at Alpha Delta was very helpful and received quick responses with questions I had.
