435 ant question

[Chad Phillips <cphillips@xxxxxxxxxxxxxxxxxxx>]

Im building a cp beam for 435 to use at demonstrations. I need help with the
phase harness. I know you can use 50ohm and 75ohm coax. What I forget is the
lengths you use to make it 90deg. Also did anyone make a polarization switch??
How did you do it??

Thanks in adcance,
Chad Phillips
