I have just ordered this antenna. I had one a year ago and wasn't up to date on how to set up and use it. while checking SWR I heard a guy in Rd Island checking Flat side of beams. I'm in South Carolina and He sounded like he was local on flat side. This antenna talks & receives on Vertical & Horizontal very good. I just ordered new one now that I know more about antenna's is adjusted by Opening or closing the oval shape of top of antenna LoopsTry going here;
Signal Engineering - The Evolution of High Performance CB Antennas!
to find out more about that antenna. No idea how it's normally tuned so I can't be any help there.

(I would advise taking the advertisement with a very large dose of 'salts'! It will transmit, after that, it's a bunch of what you spread on a garden.)
