Comparing Greyline HF Vertical Antenna to well-known antennas such as the Hy-gain AV-680 and Cushcraft R9:
*The Red inner rings are 80M, blue 40M, green 20M, and orange 10M.
Comparing Greyline Performance HF vertical antenna & HOA Flagpole Antenna to the famed 43-foot vertical

SUMMARY: Bigger is not always better. Ground-mounted verticals are great antennas and have their usefulness. Be prepared to get the radial system right. Note these systems also endow stubs, coils, and other unsightly matching systems that often fail under power. None of us deserve to be called "junk guy" by the XYL, family, or neighbors. Consider Smart, Strong, and Elegant.
GROUNDING: As always, when considering your grounding of the Flagpole Antenna plans, follow the ARRL RF Guidelines.

DX: Low Rates (examples available at checkout. Test it!)

73 Greyline Performance
I ordered Greyline’ 28’ OCF Vertical Dipole October 25,2018 (Order #FP-55221014) I erected antenna in Happy Valley, Oregon (there is pix on their website). I am an 82-year-old Retired Episcopal Priest and did assembly myself which is good for this Extra Class ‘appliance operator’. This year we had a strange wind/ice storm which brought down some trees and large tree limbs, including all my antennas. It was a unique happening for ice formed very quickly and I could not lower flag which turned into a huge block of ice contributing to taking down my vertical flagpole antenna. I contacted Greyline about purchasing several sections and hardware for an attempted repair. Before getting any specific answer concerning needed parts, I got e-mail that package had been sent from Greyline. I was confused until a thirty-pound carton appeared on my front porch. Greyline had replaced my 28’ Flagpole Antenna, no questions asked. I never thought about this on Greyline’s first page of advertising for 28' DX Flagpole Antenna, Stealth HOA Vertical Antenna No Radials 160-6M
• Industry-leading 4-year warranty
Just wanted you to know --- Greyline replaced my Vertical Antenna --- No Questions asked! By the way it also Works!
