I made several EFHW 11 meters antennas without counterpoise, but always used, or advised those for whom I made them to use a choke with them. I experimented with radials to check for any noticeable performance differences and used my analyzer to attempt to note matching changes. I don't recall anything noticeable UNTIL I worked painstakingly readjusting the variable cap and inductor tap point of my matcher with a full set of radials around the bottom. I did not see increased db of gain as I have no means of testing any such other than a radio S meter, but it was quieter with a lower noise floor, and responded to fainter rx signals, and I got excellent tx reports. I found it to be a really good antenna rivaling the 5/8^ antennas I had made.[ATTACH=full]20808[/ATTACH]
My experience is purely anecdotal, but it represents what my antennas were about - HOMEBREW usabilty. This one was excellent in that respect.
