Why is RF400 from Connex is a good alternative to LMR400?

RF400 is a European manufactured 50-ohm coaxial cable commonly used in RF communications (Wi-Fi, 4G 5G, IoT applications, 2-way radios, repeaters, etc.) and can be used as an effective alternative to LMR400. Connex terminates RF400 very low loss coaxial cables in-house to order with N-Type, SMA, RP-SMA and TNC connectors.

Here’s why RF400 is an alternative very low loss coaxial cable worth considering:

1. Electrical Performance
•    Attenuation (loss per 100m): Both cables are virtually identical across most frequencies.
•    Impedance & VSWR: Both maintain 50 Ω with very low VSWR, making them suitable for higher-frequency applications up to 6 GHz.

2. Physical Characteristics
•    Size & Bend Radius: RF400 has the same outer diameter (10.2mm) and bend radius as LMR400, so it fits the same connectors and installation requirements.
•    Flexibility: Like LMR400, RF400 is more flexible than many solid-core coaxial cables but still maintains low loss.

3. Shielding Effectiveness
•    Both use foil + braid shielding, giving >90 dB shielding effectiveness. This offers better resistance to interference.

4. Connector Compatibility
•    RF400 accepts all standard LMR400 connectors (N-type, SMA, TNC, etc.), so installers don’t need special tools or proprietary parts.

5. Cost
•    RF400 is often more affordable than LMR400 while delivering comparable performance. For longer cable runs, the cost savings can be significant.

In summary, 
RF400 is a good alternative to LMR400 because:
•    It matches performance specs (low loss, shielding, frequency range).
•    It has the same size and connectors (easy swap).
•    It’s more cost effective
