Amateur Antennas

Dipole Antenna:
Simple and widely used, consists of a wire or tubing cut to half the wavelength of the desired frequency, requires two supports, often trees or masts, can be oriented horizontally or vertically.

Yagi-Uda Antenna (Yagi):
Directional antenna with high gain, consists of a driven element and several parasitic elements (director and reflector), excellent for point-to-point communication.

Vertical Antenna:
Suitable for limited space, typically uses a vertical radiating element above a ground plane, ground-mounted or elevated (e.g., on a rooftop).

Loop Antenna:
Forms a closed loop of wire, can be tuned for specific frequencies, compact and effective for limited space.

Log-Periodic Antenna:
Wideband antenna with elements of varying lengths, suitable for multiband operation, directional characteristics.

Wire Beam Antenna:
Variant of the Yagi-Uda antenna using wire elements, can be more easily constructed and adjusted than a Yagi.

Hex Beam Antenna:
Compact directional antenna with a hexagonal shape, provides good performance with a small footprint.

Ground Plane Antenna:
Simple vertical antenna with radials forming a ground plane, suitable for handheld transceivers or mobile installations.

Quad Antenna:
Similar to a Yagi but with a square shape, provides good gain and directivity.

Rhombic Antenna:
High-gain, multi-band antenna, typically used for long-distance communication.


When choosing an amateur radio antenna, consider factors such as the frequency bands you plan to operate on, available space, local zoning regulations, and your specific communication needs. Additionally, factors like antenna height, orientation, and feedline type can influence the performance of the antenna system. Experimentation and testing are often part of optimizing antenna performance for a given location and operating conditions.


Vertical Antennas

Vertical antennas are popular choices for HF (high-frequency) bands in amateur radio due to their simplicity, ease of installation, and effectiveness for certain types of propagation. Here are some common HF vertical antenna options and the bands they are commonly used on:

Ground-Plane Verticals:

Frequency Bands: Typically used on 10 meters, 15 meters, and 20 meters.

Description: Ground-plane vertical antennas are relatively simple antennas that consist of a vertical radiator and radials that are mounted on or near the ground. They are efficient and easy to construct.

Quarter-Wave Verticals:

Frequency Bands: Can be designed for various bands, commonly used on 40 meters and 80 meters.

Description: A quarter-wave vertical antenna is a vertical radiator approximately one-quarter of a wavelength long. It often requires a good ground system for optimal performance.

Vertical Dipole Antennas:

Frequency Bands: Can be designed for various bands, commonly used on 20 meters, 40 meters, and 80 meters.

Description: A vertical dipole consists of two vertical elements, each one-quarter wavelength long, arranged in a dipole configuration. It is sometimes called an “inverted L” antenna.

Multiband Vertical Antennas:

Frequency Bands: Designed to cover multiple bands, such as 10 meters through 80 meters.

Description: These antennas are often designed with traps or other matching networks to allow operation on several bands. They offer the advantage of covering multiple bands with a single antenna.

End-Fed Half-Wave Antennas:

Frequency Bands: Can be designed for various bands, commonly used on 20 meters, 40 meters, and 80 meters.

Description: An end-fed half-wave antenna is a single-wire antenna that is resonant on a specific band. It is often used in a vertical or sloping configuration.

Vertical Yagi Antennas:

Frequency Bands: Various bands, depending on the design.

Description: While Yagi antennas are typically associated with horizontal configurations, there are vertical Yagi designs, especially for VHF and UHF. They can be used on HF bands for specific directional applications.


When selecting a vertical antenna for HF bands, it’s important to consider factors such as available space, ground conductivity, and the desired bands of operation. Additionally, an efficient ground radial system is often crucial for the performance of vertical antennas. Experimentation and tuning may be necessary to achieve optimal results for a specific location and set of operating conditions.
