Series on Basic Technician-Level RF Equations

I want to begin a series of explanations for RF and microwave formulas and equations.  But without going into all of the heavy math, we want to keep this to simple algebra.  That way, students and technicians who are starting their career the same way I did can take a practical approach and not be intimidated by the higher order calculus, transforms, etc.  These concepts are important but not so relevant at the test bench level where practical tuning methods overtake theoretical proofs.
