Which of the following is a characteristic of using a gamma match with a Yagi antenna?
It does not require the driven element to be insulated from the boom✓Bonne réponse
It does not require any inductors or capacitors
It is useful for matching multiband antennas
All these choices are correct
Explication
A gamma match connects the coax shield to the electrical center of the driven element, which is a voltage null, so the element can be bolted straight to a grounded boom without insulation. It does use a series capacitor, so the claim that it needs no inductors or capacitors is wrong.
