No Ground 27MC Antennas

No Ground Plane 27MC antennas – Reliable CB communication without ground

Do you have a vehicle or vessel without a metal chassis or surface? Then you need a No Ground Plane (NGP) 27MC antenna. These antennas are specifically designed for situations where there's no suitable metal ground plane – ideal for use on fiberglass RVs, boats, motorcycles, and caravans.

What is a No Ground Plane antenna?

A No Ground Plane antenna operates without direct contact with a metal vehicle body or chassis. Instead of a traditional ground connection, an NGP antenna uses the coaxial cable (shield) as a counter pole. This prevents high SWR values and damage to your equipment.

If you use a standard CB antenna on a vehicle without ground, you risk:

• Poor performance and short transmission range
• High SWR (Standing Wave Ratio)
• Possible damage to your transceiver

When do you use a No Ground 27MC antenna?

• Fiberglass vehicles such as campers, caravans and motorhomes
  
• Boats with plastic or fiberglass hulls
  
• Engines and vehicles without a metal body
  
• Campers with a superstructure in which the antenna is not placed on the metal vehicle part
  
• Installations where a suitable ground surface is not possible

Key Benefits of NGP Antennas

• Universally applicable on non-conductive surfaces
• Complete kits available including NGP coaxial cable
• Good performance despite lack of mass
• Easy installation without additional ground connections
• Safe for your equipment, prevents harmful SWR reflections

Does a No Ground Plane antenna have less range?

Although an NGP antenna is slightly less efficient than a standard antenna with a full metal ground plane, it's the best and safest solution in situations without ground. You maintain a reliable transmission and reception signal without any technical risks.

Brands and applications

Deltron supplies high-quality NGP antennas from trusted brands for use on:

• Campers (surface mounting)
• Boats (plastic hulls)
• Off-road and 4x4 (mounting in different positions)
• Motorcycles (small, low-mass vehicles)
• Smooth trucks or coated vehicles

Note: Always use the supplied NGP coaxial cable – it is essential for correct operation.

FAQ – Frequently Asked Questions about NGP Antennas

1. When do I need a No Ground Plane antenna?
   If your vehicle or boat does not have a metal surface under or around the antenna, an NGP antenna is the only right choice to avoid high SWR.
2. Can I use an NGP antenna on a metal vehicle?
   No, an NGP antenna is specifically designed for use without a ground. A standard CB antenna works better on a metal vehicle.
3. Can I install an NGP kit myself?
   Yes, NGP antennas are often supplied as a complete set with coax, connectors, and clear instructions. Choosing a good mounting position is important.
4. What if my signal is weak?
   Check that your NGP cable is connected correctly, or consider a longer antenna or a higher mounting position. A small power amplifier can sometimes help as well.
