I wonder if that 10m height limit is the maximum below which you don't need to apply for permission. There was something similar in UK I recall, think it had to do with height of property roof etc.

I like that in Thailand my station licence comes with a permit for up to 60m :)

Not in this part of there world, there ain't no 10m limit.

Most suburban masts are around 15m to 20m high. All applications are
assessed on an individual basis. There are moves afoot to have a 10m
minimum ratified across the country but that has not happened yet. If
it does, it means, you will not have to ask for permission to put up a
mast of that height. Anything bigger, you'll have to ask.

Of course, in rural areas, the sky is the limit.

<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.
