Note 1- that any length 50 ohm coax maybe connected to the end of these matching stubs.
Note 2- Some experimentation may be required in adjusting each matching stub to optimize the
impedance transformation.
Note 3- 17 meters should not require any stub and match okay with 50 ohm cable.
For ¾ wave lengths multiply the lengths above by a factor of 3, excess cable may be
coiled into a 6 inch dia. Coil and taped together.
