How does Greyline compare to the 43-foot vertical antenna with radials?
Bigger is not necessarily better. Look at this radiation pattern graphic: This graphic compares the Greyline OCF Vertical Dipoles (20' and 28' Flagpole Antenna) requiring No Radials by Greyline versus the very popular 43' Vertical Antenna with 20 radials. The colored bands draw the gain and ... -
Comparing the various Greyline Flagpole, Vertical Dipole Antennas
What is the difference between each Greyline Performance Antenna System? Graphic: Performance differences between the various Greyline Vertical antennas: Looking carefully at the graph for the angle of signal and antenna gain comparisons you'll notice incremental increases in depth of signal p... -
What's the difference between the DX Flagpole vs the 20' base-fed vertical with 16 buried radials?
Sure, we get folks asking about the performance differences of the shorter antennas on the bands, especially the low bands. After all, low bands require height and length, right? Yep. 80M requires 66' and 160M is 135' of wire at 1/4 wavelength. That's a tall tower or tree! If you are like mos... -
Various Mounting Locations, Gain Assumptions, and Angles of Radiation for Greyline Vertical Antennas
Radiation Patterns for Greyline Antennas mounted at Ground Level, House Eave, House Peak, and Tower Tops How does the 20' Flagpole Antenna, HF Vertical Dipole play at varying install heights and locations? We receive questions from our customers such as "Can I mount this on my roof? Near a tr... -
All bands, really? Yes, 11 Ham Radio Bands from 160-6M including WARC Bands, MARS, EMCOMM, etc. Low loss and high performance on 11 amateur radio bands from 1.8 MHz to 50 MHz including WARC Bands (even 60 meters) are now possible from anywhere and for anyone using Greyline Performance Antenna ...

Does the Flagpole Antenna work on the WARC Bands? Yes.
Yes, Greyline Performance Vertical Dipole Antennas work on all the bands, 1.8 MHz through to 50 MHz. In fact, so far, our 12, 16, 20, 24, and 28-foot tall Flagpole Antennas and HF Vertical antennas radiate a respectable signal from 160-6 meters. This includes the WARC bands and 60M, 30M, 17M... -
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 ...
