Diamond Antennas - now offers a BB7V and
BB6W VERTICAL NO-COUNTERPOISE HF ANTENNA - for the ham
bands. They look to be built very well.

I would want a lot more info before spending any money.
The BB7V is priced at US$400. It's a 22 foot vertical aluminum radiator
with a nice mast clamp (mast not included) and a cylindrical feedpoint
device.
The big question is: What's in the feedpoint device?
None of the literature gives any detail on how the feedpoint device
converts the complex impedance at the bottom of the 22 foot vertical
radiator into 50 ohms. SWR of 2 or less from 2 to 30 MHz is claimed.
The feedpoint device does not have any external controls or indications.
The radiator and mast clamp assembly can't be worth more than $100
retail. So what is in the feedpoint device that is worth $300?
The name "Maxx-Comm" comes to mind.....
