cell booster cable

Cell Booster Cable is an important component in the cell phone signal booster. Cell Booster Cable is popularly known as LMR Cable.

These are also called coax cables. Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers to their antennas, computer network connections, digital audio, and the distribution of cable television signals.

One advantage of coaxial over other types of the radio transmission line is that in an ideal coaxial cable the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors.

This allows coaxial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other types of transmission lines. Coaxial cable also provides protection of the signal from external electromagnetic interference.

In a mobile signal booster, it is important that it doesn’t interfere with other radio signals.

LMR standard is one of UV Resistant Polyethylene jacketed cables with a 20-year outdoor usage time period. LMR400 UF offers much better flexibility in comparison to corrugated and air-dielectric hard-line cables.

Rather flexible outer conductor allows the smallest bend radius possible for any similar cable in terms of size and performance. Note that LMR400 is stiffer than LMR400UF (UltraFlex) due to its solid center conductor.

In comparison to semi rigid hard-line cables, LMR400 has quite a similar loss while sporting much better loss characteristics among other flexible cables.

The multi-layered outer foil conductor has rated approximately at > 90 dB. RF Shielding is 50 dB.
