What is a major disadvantage of a quad antenna, as compared to a Yagi antenna with the same number of elements and boom length?
- ALower gain
- BRequires matching to the transmission line
- CMore susceptible to weather damage
- DRequires a more heavy-duty mast or tower
Correct answer: C — More susceptible to weather damage. From the official ISED question bank, verified word for word.
Why
A quad antenna uses wire loops stretched on a frame, creating large flat surfaces that catch heavy wind and ice more easily than the thin rods of a Yagi. The full explanation — and one for every question — is in Pro.
