Which of the following is a characteristic of using a gamma match with a Yagi antenna?

Answer: A. It does not require the driven element to be insulated from the boom

A gamma match connects to the driven element at its center and at a point along it, so the element can be mounted directly to a metal boom without insulation. It does use a capacitor, so it is not free of components.

Tip: Gamma match: no insulation needed on the boom.
