Precisely correct Peter!
If the HF antenna lobe take-off angle is fortuitously optimal for enabling a
given DX hop path then QRP Tx power will wing it!
No amount of Tx power or Rx sensitivity / SNR will compensate if this sweet
spot in the prevailing ephemeral propagation path is missed...

You can´t compare antenna gain with transmit power.
Antenna gain is one part but more important is the different elevation
angles a directive antenna or the right antenna can supply.
You can´t hear with power anyway.
And that applies to any band.

## The 1.5 kw amp is exactly 11.76 db louder than 100 watts. And thats
a real 11.76 db, not icom db. The 1.5 kw amp will work on TX on all NINE
amateur bands....
something the long boom, megabuck 20m yagi wont do. You cant work em if you
cant hear em. Well you cant work em if they cant hear you ! If station A
cant hear station B, and vice versa.....and both are running 100 watts, the
quick fix is to install a 6 to 11.76 db gain amp at both ends of the
circuit. That's cheaper vs installing a bigger ant.
