Howdy, TowerTalkians - Can anyone shed some light onto the verticals from Greyline Performance? The rationale presented sounds reasonable and I'd like some feedback onto how they actually work.
Steve What follows is MY OPINION take it for what it for what you paid for it which is nothing Verticals on 160 are the preferred DX (transmitting) antenna greyline or otherwise. Some well know DX'rs
I suspect he was asking about antennas from https://greylineperformance.com/ not how the performed during Greyling Propagation. Ron, WV4P _______________________________________________ _____________

Hi Steve, The website describes these as vertical dipoles. That suggests that they are helically loaded. Vertical dipoles don't need radials. They can center fed or off-center fed. The tallest of the
All No direct experience on this, but the reports are the customer interface for Greyline is spotty at best. Typical to get immediately charged on the credit card and getting the product 4+ months la
A better way to describe these is that they are an off center fed vertical dipole. No helical loading. They are working on a 40 ft version. I'm seriously considering a 28 ft one over salt water. Tu
After reading their web site, I have to say that their claims sound like a lot of unfounded fluff. They claim "lower noise", which is completely vague and physically unlikely for a vertical. They cla

These claims remind me of the Gotham V-80 Vertical I purchased in 1962. Knowing nothing about antennas at the time, I believed their PR copy that radials were not needed. Suffice it to say it did not
A point of clarification. There ARE a number of monoband and multiband vertical dipoles with decent performance, and as a class of antenna, vertical dipoles do NOT need radials. Most of them use some
I have the N0AX/K7LXC books. As Jim states they are excellent. All of their vertical tests were done with an extensive radial field. Even the antennas that claim to not need radials. I understand the
I have a F12 Sigma 80 antenna, which is an OCF vertical dipole with inductive loading at the feed point and a hairpin match. While it *requires* a common-mode choke at the feed point, it works very w

I have used Force 12 vertical dipoles on two DXpeditions, with excellent results. In 2004 I went to Falkland Islands and carried a Force 12 40XK. It was one of three antennas we used. It actually pro

Holy colossal vertical dipole! You guys were serious. N6BT made his antenna with pretty stout aluminum, and you found out why. It was a bear carrying it from Houston to London to Malta, but worth the

Yeah, it's probably the best built antenna I've seen short of towers as antennas. It's quite heavy, too. I can see why you chose to not schlep it back to the States. I hope it's serving the local clu
I have not heard of Greyline until now, the listed specs for their 12' antenna are incredible: Strong, Smart, Elegant design. "Pretty" premium aluminum, No messy stubs, coils, etc. Premium-only, Made
