Why Can't I Understand Or Get More Information For My Uniden Pro 520 Xl?

Hi, I have found Help Owl here on the internet with a Google search. There is a whole list of what look like links from who knows who...Cubans, Libyans, Russians...? I joined here because one idea I had was to make a modification. One that would improve performance without damaging the unit or breaking any laws. I clicked on Pro 520 XL mods to see what I could find but it brings back The owners manual in English. Then, as a result, it dawned on me that maybe modifications are really a great idea especially on consumer equipment that some may think is out of date. Like the CB radio craze is gone. Then I looked at a link like Pro 520 XL antenna. My idea was move away from doing something technical which may or may not cost me money and may or may not require some technical knowledge or skills that I am not sure how to appraise if I posses to something like more systems oriented or plug and play if you will. Maybe you have a similar understanding of what I am driving at. Like buy an antenna that is meant for the Uniden Pro 520 XL and simply connect it the radio and utilize it the way it is sold. I keep getting the same result regardless of what link I click on: The owners manual in English. I am including the link here, I am not sure if you will see it. I am mainly interested in why all of the link s bring back the same page. I am also interested in learning what your opinions or thoughts or ideas are about how to approach equipment, as, what I will sort of call, an end user, or a little bit technically, like trying performance improvements with only some knowledge, without really knowing if it requires an engineer or a business administration person to know what to do or how to think about things. Maybe I am educating you and revealing a lack of knowledge which I should regret but here you have it. Here is the link to show what I am talking about: https://www.helpowl.com/p/Uniden/PRO520XL/Research...Kind Regards,PaulIf you don't mind when you answer me if you could provide your email so that I can continue a conversation or if not, hopefully I will find a place to reply to you here on Help Owl.P.S. At the risk of sounding very naive, I want to know if you calculate and apply or charge interest or fees for looking into this.
