Super unit!
|
Time owned: 0 to 3 months
|
Out of the bag, up 35' in an unadjusted inverted V configuration, back across the yard to my "Shattick" read attic shack, to hook up and check VSWR and start multiple trips to & fro for tweaking.
I found tweaking was mostly unneeded and I made a 10 meter phone contact from MD to NM on about 30 watts with a S-9 to +10 signal report. Nuff said.
The component quality is all first rate and was well above my expectations for this price point.
Bottom line? Buy it, you will be happy you did.

Excellent Choice
|
Time owned: 3 to 6 months
|

I am running 90 watts from my Kenwood TS-450S into the DX-EE parallel dipole. Since October have 42 countries, with great signal reports from Russia, Japan (my QTH is Nanaimo, BC, Canada). The antenna performs extremely well - especially considering my sub-optimal installation (below roof line only 12 feet above the ground). 20, 15, 10 particularly great, 40 meters good enough for a working guy.

REVISED REVIEW
|
Time owned: 6 to 12 months
|
|
This antenna does a very good job being in the attic. It's probably twenty plus feet hight and is extended with the ends inverted East -West. Using an antenna tuner you can do just about all areas of the bands. I had found that is was resonant on 20 and 15 meters and you could get away without a tuner. The 40 meter band does actually work with a tuner up to about 7.250, and then you need a wide external tuner. Even my Palstar Auto AT gave up so I switched radios and used my Tokyo Hy-Power Labs HC-200AT. All was tamed for 100 watts. I checked a 15 meter station against my outside located vertical dipole and the difference was a few S units between 15 and 20. The audio was great on either antenna. I think this antenna is a bargain for what it does.

Very satisfactory for attic installation
|
Time owned: 0 to 3 months
|
|
All bands had SWR readings of no greater than 2:1, and commonly 1.5:1 for the CW portions. Erratic SWR readings were initially experienced on 40 meters. Changing the installation from an inverted vee to flattop along with shortening the length a few inches appeared to help bring the SWR down to acceptable levels. I have fair to good signal reports and have been quite satisfied with the results.

Really like mine
|
Time owned: more than 12 months
|
I use the DX-EE on my vintage station -- mostly SSB. The 4 bands are a great match for the KWM-2A and I enjoy it thououghly. Mine is a text book inverted Vee with a 90* apex at 33 feet (1/4 wave for 40M and 1/2 wave for 20M). The end supports are 20 feet from the center mast and 13 feet high. So each "leg" is 20 ft vertical and 20 feet horizontal. This puts the wire part in the clear with the end insulators about 16 or 18 feet high. The wire run east/west --- but it radiates well in all directions due to the 90* apex. It's under several huge trees that are 2 or 3 times its height -- but I work lots of Qs on all 4 bands easily.
I did raise and lower it a few times and use an analyzer to get it resonant where I wanted it. The materials are first class quality in every respect and adjusting it was easy. It's been up over a year in FL sun and storms and shows zero signs of wear. I'm confident it will be up -- and my primary antenna -- for many years.
Due to the loading coils 40M is narrower bandwidth than a full length dipole would be -- so you have a choice -- either cover the phone band or the CW band. 20 and 15 cover the entire band. 10 (since it's such a wide band) you have to choose to favor CW or phone somewhat. I chose a compromise and got it resonant at 28.350. So it covers (my definition of "covers" is under 2:1 SWR without a tuner) 40 phone, all of 20, all of 15, and from about 28.1 to 28.6 on 10M.
Our county EOC has the "big brother" and it too is excellant. Several of us felt strongly enough about Alpha-Delta to insist the primary HF antenna be the 80 - 10 version. It's been up 6 months and working nicely and we have no regrets about choosing it.

Very Solid Antenna
|
Time owned: more than 12 months
|
|
I have been using the DX EE since Sept. 21,2009 and have found it to be a very solid antenna. The intial adjustment was a snap to bring 40 meters to the portion of the phone band I use most. The external auto tuner I use takes care of the rest. Mounted as a flat top about 25 feet high at my SE Penna. QTH over 700 contacts between USA and worldwide. Most ops are very surprised to find out the antenna I am using with 100 watts.

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

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.

Beter than expected
|
Time owned: 6 to 12 months

I have mine as an inverted vee. The apex is 32 feet high on a TV mast. The ends are 20 ft away and 12 feet high so it's a perfect vee --- 90* at the apex and 1/4 wave high on 40M. The wires run due east/west.
I did raise/lower/tune it a few times to get resonance where I wanted it. Without a tuner it is less than 2.5:1 on the 40M phone band; all of 20M; all of 15M; and from 28.100 to 28.750 on 10M. Tuning consisted of changing the 40M wire by pulling it thru the end insulators and wrapping it on itself. No cutting or soldering -- so I could easily redo it if I change the frequencies I prefer. The basic tuner in my IC-746PRO is good enough to widen the DX-EE as much as I want on 40-20-15-10. Since the coax is tight to the TV mast I haven't tried the WARC bands and a wide range tuner. Any radiation on the coax would go into the mast and not the air -- so I'm happy with the "basic 4". But if your coax was hanging in the clear you wouldn't care about RF on the shield too much and no doubt the wide range tuner would give you even more.
Performance it great. As omnidirectional as you can tell based on QSOs worked. I do equally well into Europe or the west or South America or Canada from my central FL QTH. Easy QSOs often on one call and easy checking into nets and getting good reports. I run 100 watts and the antenna is within a few feet of the house and under trees 2 or 3 times its height ......... so it's not the rig or my rare location (north central FL is not on anyone's needed list) or my high and clear QTH landscape. The antenna is very well made which is critical here as we are an area with lots of storms and wind and I have limited mobility so I'm not able to do much antenna work without lots of help. I expect it will be my primary radiator for a long time.
