What is the reception pattern of a vertical antenna?

🔍 Key Concepts

• Antenna radiation pattern – how an antenna sends/receives energy in space • Difference between vertical and horizontal polarization and their usual coverage patterns • What nondirectional with regard to compass points means (azimuth vs elevation)

💭 Think About

• Think about how a vertical antenna on a ship typically covers the surrounding horizon – is it trying to talk mostly straight up, or mostly out toward other vessels and shore stations? • When someone says an antenna is nondirectional with respect to compass points, are they talking about how it behaves around the horizon (azimuth) or up-and-down (elevation)? • If a vertical antenna radiated mainly straight up, would that be useful for normal marine VHF communications between ships and shore?

✅ Before You Answer

• Clarify whether the question is asking about the vertical (up–down) vs horizontal (around the horizon) pattern • Decide if marine communications are primarily ground/horizon wave or straight up to the sky • Check which option clearly describes a vertical antenna’s usual pattern around the horizon, not just the name of a specific type of antenna

What is the reception pattern of a vertical antenna?

It has minimum radiation or reception vertically

A vertical Jackson antenna has a pattern which is nondirectional with regard to all compass points

It has maximum radiation or reception vertically

None of the above
