V-Antenna: Advantages and Disadvantages

This page covers the advantages and disadvantages of a V-antenna. It details the benefits and drawbacks of this antenna type.

What is a V-Antenna?

Introduction:

• The V-antenna is a type of long-wire antenna.
• It is constructed by arranging a long wire in a V-shaped pattern.
• It consists of two beverage antennas separated by an angle and fed from a balanced line.
• It’s often used as a bi-directional resonant antenna.
• V-antennas typically operate in the high-frequency (HF) range, usually from 3 to 30 MHz.
• The antenna impedance is around 800 Ohms.

• Based on their construction, V-antennas can be categorized into the following types:

  1. Standing wave V-antenna
  2. Traveling wave V-antenna
  3. Double Traveling wave V-antenna

Benefits or Advantages of V-Antenna

The following are the benefits or advantages of using a V-antenna:

• It has a simple construction.
• It offers high gain.
• It has a low manufacturing cost, making it less expensive overall.
• It offers higher bandwidth when the antenna is terminated.

Drawbacks or Disadvantages of V-Antenna

The following are the drawbacks or disadvantages of using a V-antenna:

• Standing waves are formed due to its design.
• Strong minor lobes are generated.
• V-antennas are typically used for fixed-frequency installations.
• It offers lower efficiency.
• While it uses low supporting structures, it requires large areas for installation.
• Horizontal beamwidth and elevation point are not separately controlled; they are mutually dependent on the array geometry.
