Which antenna type is commonly used for general portable use with a manpack radio?

• A. Dipole for base station installations.
• B. Ground-plane or top-loaded monopole for mobile or mast-mounted operations.
• C. Quarter-wave whip for general portable use.
• D. Large parabolic dish for satellite links.

Answer: (C)

In portable field use, you want a compact, lightweight vertical radiator that you can deploy quickly without special infrastructure. A quarter-wave whip fits that need perfectly: its length is about one-quarter of the wavelength of the operating frequency, giving a simple, single vertical rod that can be mounted directly on the radio or on a small mast, using the operator’s body or equipment as the counterpoise. This keeps the antenna easy to carry and set up while still providing efficient radiation for general communications.

The other options require more bulky or fixed configurations: a dipole needs two elements and careful spacing, making it less practical for a manpack; a ground-plane or top-loaded monopole relies on a substantial ground plane or mast and isn’t as portable; a large parabolic dish is heavy and designed for specialized, fixed satellite links. So the quarter-wave whip is the practical standard for general portable use.
