0.250" Semi‑Rigid RF Cable 50 Ohm Non‑Magnetic SR‑250C Coax Cable for Defense Systems

SR‑250C semi‑rigid rf cable is a 0.250", 50‑ohm, non‑magnetic coax cable engineered for very high power and low loss applications over extended distances. Its large outer diameter, solid‑metal construction, and carefully controlled dielectric system minimize attenuation and VSWR, making it ideal for backbone RF feeds, high‑duty transmit paths, and mission‑critical links. By using non‑magnetic metals throughout, SR‑250C maintains a negligible magnetic signature, which is essential in MRI/NMR suites, scientific facilities, and environments with strong or carefully controlled magnetic fields. The cable’s semi‑rigid design supports precise forming, excellent shielding, and stable electrical performance even under thermal cycling and vibration, enabling robust installations in demanding industrial and defense systems.

• 0.250" 50‑ohm semi‑rigid rf cable for extremely low attenuation and high continuous‑wave power handling.

• Non‑magnetic conductors and outer tube for use around strong magnets and magnetically sensitive instrumentation.

• High‑performance dielectric optimized for low loss, low dispersion, and predictable phase over frequency.

• Outstanding shielding effectiveness, supporting high isolation and low emissions in dense RF environments.

• Excellent impedance control along the entire length to maintain low return loss at high frequencies.

• Rugged, all‑metal construction for fixed installations exposed to shock, vibration, or harsh temperatures.

• Suitable for precision pre‑forming, with repeatable routing through gantries, racks, and long cable trays.

• Compatible with heavy‑duty connector interfaces designed for 0.250" semi‑rigid and high‑power terminations.

• High‑Power Transmit and Feed Networks – Use SR‑250C semi-rigid rf cable in transmitter output lines, combiners, and distribution networks where high RF power, low loss, and reliability are crucial.

• MRI / NMR Infrastructure Cabling – Ideal for non‑magnetic RF trunks between equipment rooms, magnet rooms, and control consoles, preserving SNR and avoiding magnetic interference.

• Broadcast and Communication Backbones – Suitable for main RF feeds in broadcast transmitters, high‑capacity repeaters, and fixed communication links that demand low insertion loss.

• Radar and Electronic Warfare Systems – Deployed in radar feed chains, phased‑array manifolds, and EW equipment where long, high‑power runs must maintain amplitude and phase integrity.

• Accelerator and Scientific Installations – Excellent for RF supply lines in particle accelerators, fusion projects, and large‑scale research labs with strict magnetic cleanliness requirements.

• Metrology‑Grade Reference Lines – Used as stable reference paths in calibration labs and power‑standard setups, supporting accurate measurements over long cable lengths.

• Engineered Pre‑Formed Cable Harnesses – Well‑suited for custom multi‑branch harnesses with defined routing, matched electrical lengths, and repeatable production line assembly.
