Works very well; I have the UltiMax DX Extreme 124' version.  Time owned: 3 to 6 months
I put this antenna up in an inverted "L' configuration with line isolators at both ends; it is 21' up vertically, and and 103' out horizontal to a tree. I do have several radials hooked-up to the antenna along with the use of a ground rod. It is most likely not the optimum configuration, but I consistently get good signal reports; please note I only use this antenna for 160, 80, 40, & 30 meters. I have a Hex beam for the other bands.

Excellent!  Time owned: 6 to 12 months
I have limited real estate to work with and a not so antenna friendly spouse who finally agreed to a 1 wire antenna. Needed to work all hf bands 160-10. Tall order!

Bought this and mounted it in an inverted L configuration. Total 24 ft up and 100ft horizontal sloping downward. Connected the ground lug to 6 radials in grass. Works very well. Very satisfied. Recommended it to a buddy with even less space. He bought the 83 ft one. He works 80-10 well!

Definately a good buy!

Convinced a skeptic!  Time owned: 0 to 3 months
I'm a skeptic by nature. I thought: how can a 53' piece of end-fed wire work as a decent antenna? Well, it does. The SWR readings are under 3:1 on 10, 12, 15, 17, 20, 30, 40 and 80 meters and very tunable to 1:1 with the rig's built-in tuner or an external tuner. I've not tried 160 meters as I don't have a tuner for that band. But, heck... it's a 53' piece of wire! The antenna is well-built and customer service is excellent. Questions answered quickly and fully. I only wish I had room for the longer versions of this antenna, but my city lot is just too small.

keep one in your arsenal  Time owned: more than 12 months
I've had the Ultimax DXtreme (53ft version) for over 2 years and it just works.
I use it on 20,40,75 mostly. never had trouble working any station I could hear.
Even at low heights. also makes a great field day/portable antenna.
Well built and can take a beating.

Very good!  Time owned: 3 to 6 months
I had the Ultimax 100. Worked fine, but noisy. Talked to Albert. Suggested the DXtreme model. Longer and grounded. What a difference. Mine is set up in an inverted L sloper. 100 watts. 160-10 m no problem. I even run my 2 m rig thru it. No problem. Definitely a winer.

Didn't work for me  Time owned: 0 to 3 months
Spent a lot of time trying to get decent SWR's but never could. This antenna apparently needs to be much higher than fifteen feet off the ground. I did talk to Albert several times and even sent the antenna back for him to check. I did appreciate his input and willingness to help but in the long run it just wouldn't work for me. Maybe later I can invest in some fiberglass poles and try again but for now I've taken it down and going to go back to a vertical.

Great Product and Support  Time owned: 0 to 3 months
I am inexperienced and relatively new to the hobby. I received my Ultimax DXtreme 88' antenna on April 29, 2016 after Albert promptly answered some questions I had the same day I sent my email, before I made my purchase. After installation, my SWR readings were off the scale on all bands except 20 meters. I sent the company an email with installation pictures and I asked for assistance. Albert called me promptly and he was extremely helpful. He corrected my installation mistakes, and my SWR readings were then AWESOME: 1.1 (10M), 1.1 (20M), 1.8 (40M), and 1.0 (80M). A friend recommended this antenna to me and it really works. The antenna wire is all but invisible, easy to install, and EXtremely efficient if installed properly. The Ultimax DXtreme is a great product, backed by excellent customer support. I highly recommend it.

Works great for me.....  Time owned: more than 12 months
I'm not an engineer, I'm a casual ham with limited resources. I run an Icom 7200 with an LDG tuner. I use two DXtreme's up into a pine and a beechnut tree. They are grounded with copper rods. For reasons I can't explain the beechnut tree is quieter :) . The wire is all but invisible. The components are high quality.

Using the tuner I have made contacts from 160 through 6 meters, over 100 countries, but still waiting for Antarctica.

I spoke with the owner, Albert, a few times. He went above and beyond to explain things to me in a friendly manner. For about a hundred bucks you can't go wrong.

Excellent product  Time owned: 0 to 3 months
This is my second review on this antenna. I bought the extreme 33' from Albert couple weeks ago The antenna is working great with my FT450D today I contacted Brazil and Venezuela from Miami FL with good signal reports despite the wretched conditions. Thank You again Albert 73.

Awesome performance for the money  Time owned: 0 to 3 months
I purchased the 53 ft Ultimax DXREME after seeing the performance from the smaller Ultimax 100 that I installed at a fellow hams QTH. I hung my antenna in a sloper configuration with the aerial sloping upward to about 25ft from the shack. SWR was 3.0 or better on all bands from the 6 meter FM portion to 160 meters, easily tunable with my transceiver's internal tuner. Even at 25 ft the performance exceeded my expectations. Everyone I heard on any band I could easily work with excellent receive as well as signal reports. I am impressed. I will recommend this product to all my friends.
