Product Details of LQ 300 Coaxial Cable
LQ 300 coaxial cable is a type of flexible,low-loss coaxial cable widely used in radio frequency (RF) communications. Its advantages include a good balance of lower signal loss and relatively easy handling due to its flexibility.
Features
1.Impedance：50 Ohms.
2.Cable Diameter: 0.300 inch(7.62 mm)
3.Outer Jacket Material: Polyethylene(PE)
4. Shielding:Foil & Braid (Aluminum; Copper,Tinned)
5. Operating Temperature: -40℃ to +85℃,Suitable for use in a wide range of environmental conditions.
Advantages
1.Optimized for RF Signals: The 50-ohm impedance is the standard for most RF communication equipment,ensuring efficient power transfer and signal integrity.
2.Low signal loss : The foam polyethylene (FPE) insulation is very crucial to its low loss, making it more efficient for transmitting RF signals over longer distance compared to standard cables.
3. Effective Shielding: The combination of foil and a braided shield provides excellent protection against external electromagnetic interference, which is crucial for maintaining a clean signal.
4. Durable and Versatile: The robust black polyethylene (PE) jacket offers UV and weather resistance, allowing for reliable outdoor use.
5. Good Flexibility: It is designed to be more flexible than corrugated copper cables, which simplifies routing during installation.
Typical Applications
LQ 300 is designed for antenna feeder and jumper cable applications,providing a cost-effective solution for:
