Best No Ground Plane (NGP) Antennas: Top Picks

By: Jeremy Neisser

As a radio enthusiast, I know the importance of having a reliable antenna. No Ground Plane (NGP) antennas are becoming increasingly popular among CB radio users, especially those who drive vehicles with fiberglass bodies. These antennas are designed to work without a ground plane, making them ideal for use on non-metallic surfaces.

Understanding No Ground Plane (NGP) Antennas is crucial before deciding to invest in one. These antennas are designed to work without a ground plane, which is typically provided by the metal body of a vehicle. Instead, they use a coil and capacitors to create a ground plane effect. This makes them ideal for use on fiberglass, RVs, boats, and other non-metallic surfaces.

Key Takeaways

• No Ground Plane (NGP) antennas are becoming increasingly popular among CB radio users, especially those who drive vehicles with fiberglass bodies.

• NGP antennas are designed to work without a ground plane, making them ideal for use on non-metallic surfaces.

• NGP antennas use a coil and capacitors to create a ground plane effect, making them ideal for use on fiberglass, RVs, boats, and other non-metallic surfaces.

Understanding No Ground Plane (NGP) Antennas

No Ground Plane (NGP) antennas are designed to work without a ground plane, which is a flat metal surface that acts as a reflector for the radio waves. The absence of a ground plane can cause issues with antenna performance, especially in vehicles with fiberglass or plastic bodies, or in boats with no metal hull.

NGP antennas are designed to overcome these issues by using a different type of antenna construction that does not rely on a ground plane. Instead, NGP antennas use a ground plane substitute, such as a coil or choke, to simulate the effects of a ground plane.

One of the main advantages of NGP antennas is their versatility. They can be used in a wide range of vehicles and boats, regardless of the type of body or hull material. Additionally, NGP antennas are often easier to install than traditional antennas, as they do not require a ground plane to be mounted on.

However, it is important to note that NGP antennas may not always provide the same level of performance as traditional antennas. Factors such as antenna height, location, and surrounding objects can all affect the performance of an NGP antenna. Therefore, it is important to carefully consider the specific needs of your vehicle or boat when choosing an NGP antenna.

In summary, NGP antennas are a versatile and convenient option for those in need of an antenna that does not require a ground plane. However, it is important to carefully consider the specific needs of your vehicle or boat to ensure that an NGP antenna will provide adequate performance.

Factors to Consider When Choosing NGP Antennas

When selecting a No Ground Plane (NGP) antenna, there are several factors to consider to ensure that you get the best performance and value for your money. Here are some key factors to keep in mind:

Frequency Range

The frequency range of an NGP antenna is an important consideration because it determines the types of signals that it can receive. Make sure that the antenna you choose covers the frequency range that you need. For example, if you plan to use the antenna for CB radio, it should cover the 27 MHz frequency range.

Antenna Length

The length of the antenna is another important factor to consider. In general, longer antennas provide better performance, but they may not be practical in all situations. Make sure to choose an antenna that is the right length for your needs. For example, a 4-foot antenna may be ideal for a truck, while a shorter antenna may be better suited for a car.

Material Quality

The quality of the materials used to make the antenna can have a significant impact on its performance and durability. Look for antennas that are made from high-quality materials, such as fiberglass or stainless steel. These materials are more durable and resistant to damage from the elements.

Brand Reputation

Finally, it is important to consider the reputation of the brand when choosing an NGP antenna. Look for brands that have a proven track record of producing high-quality antennas that perform well and last a long time. Some popular brands to consider include Firestik, Wilson, and K40.

By considering these factors when choosing an NGP antenna, you can ensure that you get the best performance and value for your money.

Installation Process of NGP Antennas

To install a No Ground Plane (NGP) antenna, the following steps should be followed:

1. Choose the right location for the antenna: The first step in installing an NGP antenna is to choose the right location for it. The antenna should be placed as high as possible and away from any obstacles that may block the signal. It is also important to ensure that the antenna is not installed near any metallic objects that may interfere with the signal.

2. Install the mounting bracket: Once the location for the antenna has been chosen, the next step is to install the mounting bracket. The bracket should be securely attached to the surface, using screws or bolts.

3. Connect the coaxial cable: The next step is to connect the coaxial cable to the antenna and the radio. The cable should be run from the radio to the mounting bracket and then to the antenna.

4. Ground the antenna: NGP antennas do not require a ground plane, but they still need to be grounded. The ground wire should be connected to the mounting bracket and then to a ground rod. This will help to protect the antenna and the radio from lightning strikes.

5. Test the antenna: Once the antenna has been installed, it is important to test it to ensure that it is working properly. This can be done by checking the SWR (Standing Wave Ratio) of the antenna using an SWR meter. The SWR should be as low as possible, ideally below 1.5.

By following these steps, you can install an NGP antenna and enjoy improved radio communication without the need for a ground plane.
