Metro, rail & road tunnels
Continuous radio coverage for train communication, emergency services and mobile networks underground.
Radiating coaxial cable with precisely designed slots in the outer conductor, so it works like a continuous antenna. It provides uniform radio coverage in metro and railway tunnels, mines, underground car parks and large buildings for train radio, public safety, TETRA, GSM, LTE and Wi-Fi systems.
MOQ: one drum per size (typically 500–1000 m)

Continuous radio coverage for train communication, emergency services and mobile networks underground.
Low-loss feeder and jumper cables for 4G/5G base stations, Wi-Fi, radio and antenna systems.
Power supply to motors, machines and production lines in factories, workshops and mines.
Cables are delivered on fumigated wooden drums or steel-wooden drums with both cable ends sealed by heat-shrink caps to keep moisture out. Drum length is cut to your project schedule to reduce joints and waste. Each drum is marked with type, size, length, gross/net weight and rotation direction. We load 20GP/40HQ or flat-rack containers at Ningbo or Shanghai port and support FOB, CFR, CIF and DDP terms with complete export documents and factory test reports.
TKG CHINA manufactures Leaky Feeder (Radiating) Coaxial Cable in accordance with IEC 61196-4, IEC 60332-1 / -3 and RoHS / REACH. A factory test report is supplied with every shipment, and third-party inspection can be arranged on request.
Yes. Conductor size, number of cores, colours, sheath printing, length and packaging can all be customised. OEM printing with your brand, labels and cartons is available.
The MOQ is usually one drum per size (typically 500–1000 m). Standard specifications ship within 7–20 days after deposit, and samples can be prepared within a few days.
