The Legend of W7DND's "Magic Antenna" or "DND Array" #hamr
He had a FANTASTIC signal! One I will never forget. -N4RV
I thought that might get your attention! What is that thing, you ask? That's Tom Erdmann, W7DND (SK) homebrew 40M/20M Magic Antennas. It was a "killer antenna" to say the least.
Anyone remember him? I think we'd all enjoy hearing some audio or seeing old pictures of W7DND. Please share with us!
He hand-built a vertical-yagi beam on a rotating dock (a rotating dock!) on salt water, with an arguably perfect parabolic bay facing North to South on the East Side... creating a Worldwide Legend, many would say he was the loudest thing out of W7 for many years. "He would work stuff I couldn't hear with my 3EL 40M Yagi!" says one W7 DXer.
Tom lived a few homes north of my Family's beach house in W7. Since the youngster years, I tinkered with wires and poles along, and literally in that very same beach. The signals are truly awesome and in comparing them to the Yagi I had at 50' there, often times the vertical sitting on the water's edge would hear things that just were not there on the Yagi.
We aren't promoting rotating docks (yet!) but we are offering a useful, and we think the smarter solution (see the performance data vs. other antennas on the market) for many restricted space QTH's. The DX Flagpole and Greyline Performance Vertical-Dipoles inspire the customers we talk to every day, to tell us amazing 'stories of legend' similar to Tom's story above. Stories from guys who have operated and in some cases built engineering marvels! Many of these folks are retiring to HOA regions for better weather and propagation but they are also finding the HOA restrictions don't allow much in the way of antenna farming. It's our hope the DX Flagpole makes it possible for Hams to return to the airwaves with confidence.
Whether you know someone retiring, downsizing, or maybe a new ham looking for a versatile antenna that performs with confidence, have them take a look at our DX Flagpole and of course our non-stealth, non-flag options, the Greyline Vertical-Dipole line.
At Greyline Performance, we're an RF Research Group, an Antenna Company, and hams just like you. We can be found staying up until 2 AM at Dayton talking radio theory and radio adventures. We hope you find our current and forthcoming products and services useful too. Thank you.
Please check out our Flagpole selection and just maybe you know someone that could enjoy getting back ON THE AIR. Please share our website with them. They will be glad you did.
