  • How does the Flagpole Antenna compare to other well-known antennas?

    Let's compare our Flagpole Antenna, 20' and 28' versions with the Hy-gain AV-680 and Cushcraft R9: The Red inner rings are 80M, blue 40M, green 20M, and orange 10M. You get the idea. Look at the low angle in the OCFs and that extra punch. Yep, no radials needed!. Sure, you can use radials, o...
  • All bands, really? Yes, 160-6M including the WARC bands

    All bands, really? Yes, 160-6M including WARC Bands too! Low loss and high performance on 11 bands, 1.8 MHz to 50 MHz including WARC Bands. We have ham radio operators reporting 160-6M on our 16' Greyline DX Antennas. That's 11 ham radio bands. Have you read through our Customer Reviews and Bl...

  • Are 43-foot verticals with radials better?

    Bigger is not better. Look at this... A. Bigger is not necessarily better! In this case, our DX Flagpole Antenna is less than half that height,  does NOT need radials  where the 43-foot vertical option does! Also, the OCF antennas enjoy a lower angle of radiation on many bands. (see graph...
  • What's the difference between the DX Flagpole vs the 20' base-fed vertical with 16 buried radials?

    A. We are surprised to find and report very little loss when dropping to the 16 and 12' foot designs. Look at 80 and 40M. Wow! Now those of you in restricted areas can enjoy a little more confidence in working the DX! One customer said, "Got Indonesia (YB) this morning on 40m SSB with 100 watts....
  • I have a QTH with another antenna, how does the DX Flagpole interact with other antennas?

    Q. "I have a QTH with another antenna, how does the DX Flagpole interact with other antennas?" Vertical Antennas such as our OCF vertical-dipole designs have very little interaction with Yagi's on top of the tower as verticals and horizontal antennas generally ignore each other. To be fair, any ...
