Evaluating HF Multi-Band Wire Antenna Systems
Presenter: Gary Baker, K7EMF
A: "Antenna Gain Vs Antenna System Efficiency"
1) Define Antenna Gain (Omni Pattern?)
2) Define Antenna System Efficiency
3) Conclude—Ant Gain Vs Efficiency
B: Feedline Characteristics
1) Characteristic Impedance, Matched-low SWR, Mismatched-No Simple Impedance Estimations
2) Coax-Need for Resonant Antenna—what happens when Antenna is Non-Resonant (define resonant antenna)
3) Feedline Loss Defined-Matched; Mis-Matched
4) Reflected Power—What does it really mean?
5) Feedline Acting Like A Transformer
C: System Efficiency---The Big Picture
1) Demonstrate SimNec System Modeling—Where the "Rubber meets the road"
D: Answer Questions
