<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...

##  Both VK land + germany have  a 10 meter...  aka 33 foot height limit.  That now effectively 
just destroyed amateur radio.  I dont know what take off angle  you are blathering  on about leigh.
At just 33 ft  with your height restriction.... the only angle you are  gonna have is either straight up...
or into the side of you neigbours home.   33  ft will not clear anything, and is  100%  ineffective.
Utility poles around  na are  typ 40 ft high,  with  the hv wire another 1.5 ft above that.   The typ home, 
with its well grounded chicken mesh, just beneath the stucco.  Toss in your  400  watt useless ..legal
limit, and you are doomed to failure.
