[TowerTalk] Tuning 4 square

[Zivney, Terry]

The SWR of the array will be very low throughout the  band and beyond with
the Comtek type box (hybrid-based). This is  because the mismatched power
is dissipated in the dummy load. To see the SWR of the system without the
broadbanding, try disconnecting the dummy load at the hybrid box. You should
now see the sharp SWR dip of the  system.  

If you feed the system with a transmitter, you can measure the SWR of
the system wish a wattmeter at the dummy load - the dummy load power
is the reflected power and you know the forward power from your rig,
so you can compute SWR.
