LowBand 1-1 Common Mode Choke 5000W Balun Triple Core

Excellent LowBand 1-1 Common Mode Choke 5000W Balun Triple Core for any low band antenna, including Yagi, dipoles, and vertical antennas. High common-mode impedance and extreme power rating are the key features. This balun could easily handle any linear amplifier with a single or two FU728F, GU78B, GU84, GS35B, or MRF1K5, BLF188, ART1K6, ART1K9, ART2K5.

Why use a Common Mode Choke – Current Balun?

In transmitting antenna systems, common mode currents can negatively impact antenna efficiency, reduce gain, distort the antenna pattern, and increase local radio frequency interference (RFI).

In receiving systems, common-mode currents may raise the noise floor, distort audio signals, cause computer crashes, or potentially result in RF burns.

A high-quality common-mode choke or current balun features high common-mode impedance. This high impedance helps to minimize unwanted currents to nearly undetectable levels. A general guideline suggests aiming for a common mode impedance of 500 Ohms or higher for 50 Ohm transmission lines.

 

Use this LowBand 1-1 Common Mode Choke 5000W Balun with any antenna to:

• Increase antenna efficiency
• Increase antenna gain
• Clean antenna pattern
• Lower RFI
• Lower receive noise
