// Cebik’s Moxon Turnstile as described in “A Simple Fixed Antenna for VHF-UHF Satellite Work”
// note there is a problem with quotes and double quotes — I had to copy them from another model 
// rather than typing them
// so I’ve converted to metres
// this version replaces the driven2 excitation with a 90º phasing line between driven1 and driven2
// so driven1 is excited from the middle, where the phasing line is connected
// driven2 is just connected through the phasing line
