Gary, I took your comments above from the thread on the Imax an made another thread to ask my questions about your Ringo. I've tried modeling this antenna, but there are too many dimensions missing in the link above to be sure. What is the space between the brackets? Can you describe the details for the tuning stub? They show a length. But how does it works to tune the ranges noted? It doesn't even show the length and diameter dimensions for the mounting bracket noted as the base assembly AA. It does show BB throught EE at 48" inches each which = 192" and then the overall length chart shows the overall length is 192" at the mid band. I don't get it...the base assembly does not appear to be included in the overall length except in Fig 3. There are other dimensions that are important as well if a model is to try and even get close. Maybe you help me with this?
