*LMR Series & TNC/N Connectors: 5G Backhaul's Secret Weapons*

5G's mmWave revolution is strangling legacy RF systems. Antiquated UHF  

connectors leak above 500MHz – fatal for 28GHz small cells. Enter TNC  

connectors: their threaded coupling maintains 50Ω impedance up to 15GHz while  

surviving MIL-STD-810H vibration tests.  

Macro towers demand muscle: LMR600 with N connectors handles 2.8kW average  

power – essential for massive MIMO arrays. In urban deployments, LMR240 (30%  

slimmer than LMR400) enables 12Gb/s backhaul with 4x the bend radius of rigid  

competitors.  

5G Field Kit Essentials:  

▶︎ Small Cells: LMR195 + TNC (IP68 kits)  

▶ DAS Arenas: LMR400 + 7/16 DIN (surge protected)  

▶ Legacy Upgrades: RF1.37 swaps for LMR200  

Technical Insight: LMR240 achieves 6.1dB/100m loss at 3.5GHz – 52% better than  

RG214. When mated with O-ring sealed N connectors, it passes 30-day salt spray.
