MFJ-4402 Mobile Transceiver Protector

Introducing the MFJ-4402 Mobile Transceiver Protector, a must-have accessory for any mobile radio enthusiast. This compact device is designed to safeguard your valuable mobile rig from a myriad of operating issues commonly encountered in modern vehicles. With its advanced surge protection and voltage regulation features, the MFJ-4402 ensures that your transceiver remains in optimal condition, regardless of the electrical challenges your vehicle may present.

Key Features and Specifications

The MFJ-4402 is equipped with a built-in surge protection diode that significantly reduces the risk of high voltage spikes damaging your rig due to alternator failures or accidental jumps from other vehicles. It also offers reverse polarity protection, further safeguarding your equipment. Additionally, the device addresses sagging voltages during vehicle start-up, preventing issues such as radio malfunction, loss of memory channels, and corruption of service and setup menus. A delay timer, controlled by the ignition sense line, ensures that your transceiver powers on only when the vehicle is running and a normal voltage is reached. This feature, along with the 30A fuse for over-current and reverse voltage protection, guarantees the reliability and longevity of your mobile rig.

Practical Uses and Benefits

With its AndersonPowerPolesTM connections for high-current lines and a bayonet lug for the ignition sense line, the MFJ-4402 is easy to install and compatible with a wide range of vehicles. Its compact size of 2 ⅞" x 4" x 1 ½" ensures a seamless integration into your vehicle installation. The MFJ-4402 not only protects your transceiver from electrical disturbances but also enhances your overall mobile radio experience. By preventing distorted audio, frequency shifting, and other issues that can arise from fluctuating voltages, this device ensures that your communication remains clear and uninterrupted. Upgrade your mobile rig with the MFJ-4402 and enjoy peace of mind on the road.
