The LMR-500-FR 50 Ohm flexible coax cable from Times Microwave has a Foam Polyethylene (PE) dielectric. The LMR-500-FR coax is constructed with a 12.7mm jacket made of Fire-Resistant Polyethylene (FRPE) coax has a shield count of two, a RF shielding of > 90 dB and the maximum frequency for this Time Microwave coaxial cable is 8 GHz. LMR-500-FR coax cable has an attenuation at 1 GHz of 3.3 db/100ft .

Rojone has been the Times Microwaves Australian distributor for over 35 years and can custom manufacture LMR cable assemblies to your exact needs. We have a dedicated QA department that can test cable assemblies up to 50 GHz as well as perform PIM testing at 750-800 MHz, 900MHz 2100-2200 MHz frequency.

Ideal for…
  • Jumper Assemblies in Wireless Communications Systems
  • Short Antenna Feeder runs
  • Any application (e.g. WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas) requiring an easily routed, low loss RF cable
