To ensure the best performance of a wireless LAN antenna system, signal loss needs to be kept at a minimum. A common cause of signal loss is often from the coaxial cable itself. The type and length of cable used are both determining factors that can lead to a weaker signal at the end of the cable where the antenna is connected. This leads to the introduction of Low-Loss coaxial cable. By providing better RF shielding than typical RG cable, signal loss through the cable is greatly reduced.

For example, a 2.4 GHz system using 50 feet of RG213 cable will have approximately 6 dB of loss. That is an efficiency of only 25%. L-com's CA-400 series which is the low-loss equivalent of RG213 only has 3.3 dB of loss, giving this cable an efficiency of 46.7%. That is almost half the signal loss of the RG213 cable.
The most common type of low-loss cable used for WLAN antenna systems is the 400-series type cable. L-com's CA-400 Low-Loss cable provides the perfect balance of being lightweight and small in diameter, while at the same time offering excellent low loss characteristics. Providing equal performance and mechanical characteristics from brands like CommScope/Andrew and Times Microwave, L-com's CA-400 low-loss coax is available in bulk reels of 500 or 1000 feet or can be purchased by-the-foot.
This cable is also available as Plenum rated 400-series, and for installations requiring greater flexibility, as 400-series Ultra-Flex cable. In addition to our bulk cable, L-com offers a wide variety of off the shelf cable assemblies as well as customs that can be ordered using our online custom cable configurator.
Crimp and clamp style connectors for our CA-400 cable are available in Type N (male and female), RP-SMA (male and female), RP-TNC (male and female) and other connector types, along with hand strippers, spin strippers, and crimping tools. That's everything you should need for a typical bulk cable installation. Click here to try our Radio to Connector-Type cross reference guide.
