...

i have an 500w medium waves transmitter (output 50ohm) at 1431khz. i
have the components and i have decide to construct this
http://www.tzitzikas.webs.com/match.JPG match system. it is ok? i must
connect the power/swr meter before this system (between transmitter and
match system) or after this system (between match system and antenna)?
my antenna is an inverted L 5l/16 antenna.
do you have to propose any better system? thank you

Are you allowed to operate a 500 watt transmitter in the medium wave band in
your country for student radio? That sounds a lot of power to cover a
campus.

What is a 51/16 antenna? ... is that 3.19 wavelengths long? ... if so, that
would be inefficient as a medium wave radiator.

You'll find that a pi network, as you propose, can be made to match almost
anything to anything at a spot frequency, as long as the L and Cs have
sufficient range, but you might have difficulty achieving adequate
uniformity over the nominal 9 kHz bandwidth of a normal medium-wave
transmission (i.e. a broadcast service).
