LMR 400 Coaxial Cable

  • The Times Microwave LMR-400 is a low loss braided coaxial cable.
  • This 3/8 in 50 Ohm coaxial cable has a stranded outer conductor and a bare copper centre conductor.
  • The wires in these cables are so tough that they can withstand a lot of bending and shaping without breaking.

Practical

RF coaxial cable is easy to install, very durable, and inexpensive

Stable

RF coaxial cable offers good resistance to electromagnetic interference

Universal

RF coaxial cable also perform very well over short distances such as home installations

About Cloom LRM 400 Coaxial Cable

The Cloom LMR-400 is the perfect solution for users looking to transmit data in high power HF needs, VHF/UHF applications such as WISP, WLL and GPS.

LMR-400 is a remarkable cable for the reasons that has better specifications than RG8 coaxial cables with bonded aluminium tape and gas-filled dielectric in its manufacture.

The bonded aluminium tape outer conductor is overlapped to provide 100% coverage, supported by a 90 per cent braided shield, providing around >90 dB RF shielding (>180 dB crosstalk) and superior interference immunity against ingress and egress.

We use a quality, tested and certified product that ensures your antenna has an excellent boost in output power over any other option on the market today!

LMR 400 Coaxial Cable Features

Lowest Signal Loss in Its Class

Durability

LMR-400 cables are made with PCV that can withstand UV damage and have a life expectancy of over 20 years.

Flexibility

The flexible outer conductor gives you the ability to bend it around tight corners for optimal installation.

Low loss

RG-174 loses 0.32 dB, whereas LMR-400 only losses 0.04 dB per foot at 900 MHz.

Higher frequency band

LMR-400 is an excellent choice for higher frequency applications, with custom attenuation designed to meet the needs of such frequency greater than 1GHz.

Conductivity

The effective double shield protects against electrical interference at all times.

More connector types available

It comes in a variety of colors and connector types, including common interface, reverse polarity, and solder or non-solder center pins.
