What is a delta loop antenna with parasitic elements?
- AAn antenna made of a large multi-turn triangular loop
- BAn antenna system made of three vertical antennas, arranged in a triangular shape
- CAn antenna made from several triangular coils of wire on an insulating form
- DAn antenna consisting of multiple elements, each a triangular loop whose total length is approximately one
Correct answer: D — An antenna consisting of multiple elements, each a triangular loop whose total length is approximately one. From the official ISED question bank, verified word for word.
Why
A delta loop antenna with parasitic elements works like a standard Yagi beam, but instead of straight rods, every part is shaped as a triangle. The full explanation — and one for every question — is in Pro.
