Hi all,
I'm in the process of building some halfwave verticals to use portable on HF
with the aid of a DK9SQ telescoping fibreglass pole.
I am building the LC matching system to convert the high impedance at the
end of the halfwave down to the 50ohms to match the coax.
My question is this! I'm sure in the past I have seen a computer program
that allows you to key in the frequency and it will give you the length
required and the values of inductance and capacitance required.
Does anyone know were I can locate this program or if there is a manual
calculation I can use for the LC values.
Regards
