As mentions, no option without the math if you really want to grok things.
The closest lite-math way is through amateur radio publications from ARRL. However this gloss over and skip a ton of stuff that ultimately you'll need to still learn with the math later if you really want to understand things.
We used Ramo/Whinnery/Van Duzer in school. I'm not saying good or bad. Ramo is the R in TRW if that means anything.
