Way back in my CB days, I had an M-400 (similar to the now Sirio Starduster), and I concur what Blackswan73 said, as I had strong and far reach local signal with that antenna ! (Wasn’t interested in skip).
Later I replaced it with a « Big Stick » 18ft version, placed on the same mast, and gee have I regretted the change ! I was getting full skip and my local coverage vanished.
I am thinking of getting a Sirio Starduster, just to experience again that sweet local / regional coverage !
