LMR-400 ultra low loss cables have many uses in cellular amplifier systems as they allow extension of different parts of the system without preventatively attenuating the signal. They can be connected between a cell phone amplifier and an external antenna or between an amplifier and an internal antenna. The extension between the various components of a cellular amplifier system is important because if these parts are too close this could prevent operation of your cell phone amplifier. The LMR-400cables have N/Male connectors at both ends, which connect to N/Female receptors. If you require the cable to connect to other types of receptors e.g. for other Amplifiers , then there are adapters available which can accomplish this for you. Give us a call and we can find the right cable/adapter configuration for you.
The LMR-400 ultra low loss cables come in many different sizes. To select the correct cable length for your situation, we would advise you to consider how much separation you require in your cell phone repeater system. Also, in general, using more cable than is needed should be avoided as it will cause unnecessary attenuation in your repeater system.

Extension Cable

Our extension cables are high-quality, low-loss cables designed for use with our cell repeater kits.
The cables can be placed in one of two places:
1) Between the cellular amplifier unit and directional antenna. This will extend the existing 30-foot cable.
2) Between the amplifier unit and the rebroadcast antenna.
Any extension cable used will slightly decrease the total signal strength since all cables cause signal loss (the longer the cable, the greater the loss). If you have weak cell phone signal outside your home or office (less than 3 bars) and need to use an extension cable, you should use a Antenna upgrade to avoid a decrease in your repeater system's coverage area.
