Re: LF: KITE ANT

Jean-Louis,

In UK 60m is the flying limit and 30m near an airport but I think
you'd have to be seriously daft to fly a kite near an airport anyway.
You can fly higher too.... for permission to exceed the limits stated
above you are required to complete an application form.  Details from

A high value bleed resistor with a thick conductor connector to a
ground rod should always be attached from any down lead
before entering a vehicle or property etc. Especially in Summer and if
on a hill make sure you don't emulate Franklin's proposed experiments!
