Reliable Connectivity for Broadcast and Wireless Applications
TC-400-BM-X provides a premium, classic termination method for LMR-400 coaxial cable. Utilizing a solder center pin combined with an outer crimp shield, this BNC Male connector is engineered for superior pull strength, signal integrity, and reliable performance up to 4 GHz better than RG-213 Performance.
- Secure Bayonet Lock: Features the classic BNC bayonet coupling mechanism for fast, positive locking, ensuring a secure connection that is resistant to vibration.
- Solder Center Pin: The inner contact requires soldering, which provides a permanent, low-resistance electrical connection, ideal for demanding applications or stranded center conductors.
- High Frequency Performance: Engineered for excellent VSWR performance (typically <1.35:1) with an impedance of 50 Ohms for use in applications up to 4 GHz better than RG-213 Performance.
- Robust Construction: Features a White Bronze (Albaloy) body finish and Gold-plated center pin for exceptional durability, corrosion resistance, and low signal loss.
- Time-Tested TC Style: This connector is a reliable, industry-proven design, offering maximum mechanical robustness where solderless connections are not preferred.
