    Feedback / Reviews

    We know you will be doing your homework and therefore we encourage you to read our best effort of transparency presented within the FAQs and RF BLOG entries to get a better sense of the homework we continue to conduct and present from our design, engineering, and upgrades of these OCF Vertical Antenna Systems.

    See pictures and read stories of happy customers like Steve and Bill, both of whom have been off the air for decades! To a radio store owner that ran across an “amazing signal” on 75M using the DX Flagpole Antenna!


    We bring you real customers stories like Steve who compares his DX Flagpole to his 84' End-Fed Zepp using reverse beacon RBN data and is enjoying the weekly contests and having a ball.


    Meet Bill too!  After downsizing from his multi-tower QTH, he reports running Europe and working DXpeditions on the low bands again, surpassing the results of his wire loop in the tree during signal comparison testing by 2 S units!


    You’ll hear about the European ham radio store owner who declared amazement at the signals on 75M he worked over the Atlantic coming from a “20' OCF DX Flagpole” among a group of guys with towers and wires and he was not weaker in signal strength on an otherwise noisy band! He called us on the phone to express the news!

    RF Research

    Just as much fun for us (and maybe you too) we enjoy tinkering with our designs for improvements and then present these various challenges and projects we've faced and overcome, many times with our valuable customer's wisdom and input.

    We include various topics from where best to plant your antenna and what performance measures you should expect in many situations. Measured and tested by us and our customers too in some cases. Read more about these and more, here: 

    RF Blog (see drop down menu)


    We'd like to hear from you. Let's get you and your friends back on the air with real DX confidence and a real signal just like Bill, Steve and our Peers around the world are talking about. 

    If you have any questions, please let us know. We’d love to send you a DX Antenna too!

    Can you use a high performance, agile and rugged, all band HF vertical too? We're honored to serve you.


    Thank you,
