[Amps] new amp race / antenna take-off angle

[Martin Sole]

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 :)
