LMR-900 Coaxial Cable
- LMR-900 Coaxial Cable: Lowest-Loss Standard LMR Series Cable from Times Microwave
- Ultra-Low Attenuation: 1.47 dB/100ft at 900 MHz — ideal for long antenna runs
- 50 Ohm Nominal Impedance: Compatible with all standard RF equipment
- High Power Handling: Up to 5 kW at 1 GHz for high-power transmitter feeds
- Wide Frequency Range: DC to 6 GHz — covers L, S, C, and Ku-band applications
- High Shielding Effectiveness: Over 90 dB — minimises electromagnetic interference
- Outer Diameter: 27.7mm (1.09 in) with UV-resistant polyethylene jacket
- Velocity of Propagation: 87% — genuine Times Microwave, available in custom lengths
Times Microwave LMR-900 is the largest and lowest-loss cable in the standard LMR series. With an outer diameter of 27.7mm and foam polyethylene dielectric, it delivers superior attenuation performance for long outdoor antenna runs, high-power transmitter feeds, and permanent infrastructure installations where minimising cable loss is the primary design constraint.
LMR-900 is the preferred choice for VSAT ground station feedlines, cellular base station antenna jumpers, broadcast transmitter outputs, and high-power satellite uplink systems across MENA and the GCC. Its UV-resistant black polyethylene jacket withstands the harsh outdoor conditions typical of UAE and Gulf installations.
