LCF 7/8” RF feeder cable are used as a reliable backbone for cellular radio systems including GSM, PCN/PCS, CDMA, AMPS, PDC or ETACS. Low loss cables use foam with very low dielectric losses resulting in low attenuation of RF power.
Application:
- Main feed line
- Riser-rated In-Building (JFN types)
- Low Attenuation
- Complete Shielding
- Low VSWR
- Outstanding Intermodulation Performance
- High Power Rating
- Wide Range of Application
- Typical areas of application are:
feed lines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects.
