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.
