Technical Data

  • How do Greyline DX antennas compare with each other?

    The lower bands get a little boost when going to the 28' version. The 20' version already works well on its own and when stacked against the various market competitors. With the push of a button, you are back on all bands, with ease!
  • Will this work in the FT8 mode and digital modes?

    Q. Will this work in the FT8 mode? A. YES! We see the maps of our customers cover the entire planet with FT8. No joke.Here's are three maps of live-signals around the world for you: PSK: https://pskreporter.info/pskmap.html CW: http://www.reversebeacon.net/srch.php (find any clear frequency an...
  • Do I need a tuner at the base or can a shack ATU or Rig Tuner work too?

    Q. Do I need a tuner at the base of the Flagpole Antenna or can we tune from the shack with an ATU or Rig Tuner? A. I'm glad you asked. Some people do tune the antenna from the shack and report happy results. Please keep in mind for the peak performance we showcase for this antenna, it is design...
  • Does the DX Flagpole require a balanced or unbalanced ATU tuner?

    A. This reveals a common misconception about balanced/unbalanced antenna systems. In a practical sense, all that balanced means is that a source of RF voltage/current is not connected anywhere to a ground reference. Said in a simpler way, to be balanced an RF source must "float." It is true that...
  • Is the DX Flagpole Antenna Resonant or a non-resonant Antenna?

    A. Ham radio enthusiasts generally expect an antenna to have a low SWR. Otherwise, they feel, “It won’t get out well and I might even damage my finals.” What’s your opinion? Is this a universal truth? Here, look at this: RESONANT MODE  Here the antenna is operated at or near its natural resona...
  • What is the quality of the materials of the Greyline DX antennas?

    We didn't cut any corners! Only premium materials are used throughout the system. The AI tubing is Made in the USA, double-dipped, double-walled, high-grade 6000 series aircraft-grade aluminum we are very proud of, 2-inch OD or 2.25-inch OD top to bottom, industrial-strength fiberglass insulators...
  • What is the power rating of Greyline Performance Antennas?

    Q. What is the power rating of the Flagpole Antenna and Vertical Antennas? A. The power limitation will be limited only by your choice of Antenna Tuner and Feedline from the shack and each units power rating. Some tuners are rated for low power at around 200W, others are 600W. We see a few optio...
  • What is the wind rating of the Flagpole Antenna?

    What is the wind rating of the Flagpole Antenna? A. These antennas have been engineered to withstand 90-100 MPH wind gusts according to “Guide Specifications for Design of Metal Flagpoles,” ANSI/NAAMM FP 1001-07. This was used rather than ANSI/TIA-222-G (regulating antennas and towers) as this s...
