All this is good but how about a Simplified Roundup

.

Maximum Antenna Performance (best TX & RX) Signal to the other station you're communicating with is an overall combination of these factors - audio and watts aside. Also to assume it's best signal to a LOCAL Ground Wave contact. DX not included as once you throw in variable propagation most of everything else isn't thrown out the window exactly but propagation can't ever be nailed down so as to measure.

.

Best resonance and Lowest SWR

Gain

Height Above Ground


Perfect resonance and flat SWR will provide greatest Effective Radiated Power


A Higher Gain design will beat a Lower Gain Design - A perfectly resonant 5/8 wave antenna will beat a perfectly resonant 1/4 antenna at same height and power output.


An antenna 100' above the ground will beat an antenna 30' above the ground.
