If 10 watts is delivered to a short antenna, where does it go if it is not
radiated just as well as 10 watts delivered to a long antenna?


Make it 100 Watts, make it 1000 Watts,

Transmit for 5 minutes, then switch off and measure temperature.

Is the short antenna hotter?

W.-

Yes. I use a Hustler mobile antenna with resonators for each band.
After transmitting 100 Watts, the resonator coils become hot to the
touch. It seems to be worse on the lower bands with larger resonators.
