Consider a split dipole feed (TA-33, A3, A4,)
vs. a BETA match (TH3, TH6)
vs. a capacitive (Mosley CL33)
vs. an open sleeve feed (Force 12).
Can you tell me what the *relative* phase shifts of each of these
matching systems is to each other? I wouldn't have a clue.
If you are going to aim them in different directions it doesn't matter.
But, if you want to aim them in the same direction for stacking GAIN,
you will need to be sure the driven element currents are within 30
degrees of each other. How would you go about determining this?
