At Deltron we offer an extensive selection of No Ground 27MHz antennas, perfect for vehicles and boats without metal surfaces. These antennas are designed to provide excellent performance even in the absence of a traditional metal ground plane.

What is a Ground Plane?

A ground plane is the metal surface under your antenna that is necessary for optimal signal transmission. In traditional mobile 27MHz antennas, the vehicle body acts as the ground plane. Without an adequate ground plane, an antenna will not perform optimally.

When to Use a No Ground Plane (NGP) Antenna?

If you have a vehicle or boat with a fiberglass body or little to no metal parts, such as RVs, caravans, boats and some motorcycles, you need a No Ground Plane (NGP) antenna. These antennas are specifically designed to operate without the need for a metal ground plane. NGP antennas use special NGP coaxial cables and are ideal for situations where a standard antenna would not perform sufficiently.

Benefits of No Ground Antennas

• No Metal Base Required: Perfect for vehicles and boats with fiberglass or plastic bodies.
• Easy to Install: Designed for easy installation and optimal performance without complex adjustments.
• Excellent Signal Transmission: Even without a metal base, these antennas provide reliable communications.

Applications of No Ground Antennas

Campers and Caravans: For vehicles with large plastic surfaces.
Boats: Ideal for fiberglass boats without metal deck.
Motors: For motors with little to no metal base.
Additional information

A ground plane is essential for a traditional CB antenna to work effectively, but No Ground Plane antennas provide a solution for situations where a ground plane is missing. These antennas use the coax shield as a counterpart and are therefore suitable for vehicles and boats without metal surfaces. Although NGP antennas do not perform as well as traditional CB antennas, they provide a necessary solution for difficult installation conditions.

Choose a No Ground 27MHz antenna from Deltron and ensure yourself of reliable communication, regardless of the circumstances.
