About Us

Welcome to Greyline Performance

Home of the DX Flagpole Antenna! 

Ham Radio is fun again which prompted us to offer a premium, more useful service to our peers.

"Consider Ratings listed and divide by two for most Amateur Companies," as well-known in Ham circles.

We accepted that challenge with premium-only, Made in America materials, custom design and engineering-top to bottom and the official Structural Analysis illustrates the science and math as solid and sure. Verticals are indeed cool again.


We are a small group of very active, lifelong (35+ years) ham radio enthusiasts with families and a passion for our global fraternal hobby, just like you.

Team Highlights:

- Antenna Award Winner! It's true, the ARRL "Antenna of the Year" Award was won by one of our own, a career Broadcast-RF Engineer and antenna designer extraordinaire. Congrats, John! (he addresses many of our Q&A's inside)

- Sound Engineering: Our working structural engineer has earned his chops alongside savant antenna designers in both the Ham and Professional markets, too. He's analyzed every aspect of structure and materials to be certain our claims are solid. Thank you, sir.

- Veteran Ops: Our GM has been Radioactive for 40-years and was honored to compete as a member of 'Team USA' at WRTC 2014 in Boston. He says, "I just heard that our contest station in the Caribbean uses the OCF design to compete on the world stage!" We are on the right track!

Collectively, our goal is to offer a more useful service with modern, smart antenna designs adhering to professional engineering standards, for you, our radio peer. We've heard the saying "if it's an amateur antenna business, cut the ratings in half." Yikes. Not us.

We strive to earn the public trust, your trust, by offering transparent data from real clear thinking on how best to get you 'on the air' with real DX Confidence.

UPDATE: HOA NEWS: May 2019: We are Celebrating the success of our HOA customers. We work directly with dozens of HOA's around the country (and the civilized world) interested to develop an organized understanding of how Ham Radio can play a valuable role in their communities. We played a small part in the discussions with an Arizona group as they studied our Antennas Engineering and Design data that ultimately gained final approvals to put real antennas in the air in an HOA! First HOA of its kind to achieve such levels of approval. Congrats!

Whether you are a big gun DXer, on a small city lot, on a rooftop with no room for radials, or simply desire an all band agility for your favorite mode (WSJT-X, FT8, SDR, CW, SSB, NVIS, AIS, ARES, Winlink, etc.) where other options such as putting up a tower, a wire in a 140' tree, or 130 radials on the ground just won't work for you, consider studying our products attributes of very low losses and high-performance. (yes, really!)

One thing our team has in common is that we have enjoyed various levels of exposure to the professional antenna design and engineering "arts" and have pledged interest and intent to design a suite of smart products made available right here on this website. This is fun for us!

Stay tuned as we create more solutions for you. Drop your email in the bottom right box on this page to receive our free monthly updates - you'll be glad you did. 

As your radio peers, we are 'at your service' to bring you superior engineering, smart design, and premium materials in the form of efficient multi-band antennas (like our DX Flagpole Antenna and DXV Vertical Dipole line. We think you will be pleased.
