What becomes all the energy sent by my TX on 160m ? What become de
standing
waves and reactive load ? Is it possible than all 100W are lost in the
coax
or the feeder without be emitted ?

Who could explain me this ?

Thanks

G5RV - WHERE THE POWER GOES ON 160m

Efficiency = Power into / Power out of

Efficiency % Location
========= =======
70.4 L-tuner
21.9 Coax line
78.8 Open wire line
11-6 Antenna wire and soil under anrenna

Overall radiating efficiency at 1.9 MHz = 1.40 %

or 18.5dB, or 3 S-units down relative to a very high 1/2-wave dipole.

Download program DIPOLE3 from website below. It analyses performance of any
dipole, of any length, any wire diameter at any height, and any lengths of
any types and combinations of feedlines. Also calculated are L and C
component values of L-network to match to 50 ohms.
