The type of coaxial cable you should use for your antenna depends on a few factors such as the frequency range of your antenna, the distance between your antenna and the receiver/transmitter, and the power level of your signal. However, a commonly used and reliable option for most applications is Low Loss 240 coaxial cable, which has a frequency range of up to 6 GHz and is suitable for most analog and digital signals. If you require higher performance, such as for high-frequency or long-distance applications, you may need to consider higher-grade coaxial cables such as the 400 or 600 series cable. It is recommended to consult with an expert in the field to determine the most appropriate type of coaxial cable for your specific application.  Contact GNS Wireless today so we may assist in the correct selection of coaxial cable.
