I have used many different styles of wire antennas over my 50+ years of my ham radio life. Recently I lost my antenna tree to a lightning strike, and with it my antenna. I read a lot of reviews on Ultimax Antennas, and decided to give the ULTIMAX DXTREME END-FED ANTENNA 160M to 6M 2KW 124 foot model antenna a try. I put it up in an inverted L configuration to make it fit my property. Using it with the counter poise and their line isolator. WOW! Am I impressed!! This antenna performs better than I could have hoped for! My IC-9100 built in tuner works for all the bands, even 6 meters. As I got it put up at the end of the day, I decided to try 160 meters first, and made contacts all over the U.S. On 20 meters, I was making contacts from Africa to Asia on the 1st or 2nd call.
So, long story short, I would very much and highly recommend any ULTIMAX Antenna! They are very well built, easy to put up, and works!!
Thank you Albert and ULTIMAX Antennas!

I had some antenna damage from a recent tropical store that came to land near my area. I looked at replacing the other manufacturers antenna, and was given a better price from UltiMax than the other guy. I ordered the DXTREME 88′ model and put it up with the other guys design. In comparison the DXTREME gives a fuller sounding signal versus the other antenna that has some shortening coils in its element. I will be staying with the UltiMax and adding the Line Isolator to try and avoid my neighbors A/C unit and any RFI to my electronics. The one that Albert sells is 2 S Units above the other guys antenna. Thanks for making a high quality product my friend.

I recently bought the 72 foot version of this antenna and cannot tell you how pleased I am with the quality of construction and telephone support. In addition, the deployment was very simple and now gives me great performance with my LDG AT-100 Pro II Autotuner and Ultimax Line Isolator. The owner, Albert, was with me every step of the way and is a far cry from my terrible experience with another antenna vendor. I truly trust the product and highly recommend it, Please keep in mind that the Autotuner and Line Isolator were a must have in my installation and I strongly recommend those as part of any installation. 🙂

Hi, I have the model 124ft, installed in inverted L over a tree( I used a fishing rod for it) high about 50-60 Ft. the “black box” is a 12-15inch, it is the best wire multiband antenna after 3 years and $2000.00 spent. No problems with DX, work fine all around: If I hear I work it and I don’t need to call 2 times

I purchase the ULTIMAX DXTREME END-FED ANTENNA 160M to 6M 2KW 124 foot, in June 2024 and have noticed that many spots all over the US now are able to be reached. FT-8 now populates world wide and signals are strong. I compaired to other end fed brands.and this one by far takes the prize.

I’ve just purchased the 124 foot version of this antenna, and it works quite well. Being totally blind, I had to get some sighted help to install the antenna, the my sighted help was not a ham. living on a compromised lot here in the middle of Austin Texas, installation was easy, straight forward, and just plain worked. I had a question about an issue that I was experiencing on 80 meters, and emailed support on Saturday afternoon, once the installation was completed. To my surprise on Sunday morning I received a response with some instructions that were clear and concise to help resolve the issue, which was a high SWR on 80 meters. All other bands have worked flawlessly. The staff at Ultimax Antennas are top notch, and I can’t recommend them enough. Whether your a new ham, an old timer, and you just want something to get on the air that just works, I know that any of Ultimax antenna’s solutions will be an excellent choice.
