Part number C240SP-2SMAJ from Panorama Antennas is a ready-made 2 m (6.56 ft) CS240 coax assembly with an SMA male termination on one end and an SMA female on the other. Underneath the connectors is CS240, Panorama's ultra-low-loss 6.1 mm coaxial cable with double screening. It holds signal over distances that would starve a 5 mm cable, which is why Panorama fits it to its longer extension assemblies. The SMA male end threads onto the SMA female antenna ports found on most cellular routers and gateways, including Cradlepoint, Teltonika, Digi, Peplink, and Sierra Wireless hardware. The SMA female (jack) end accepts any standard SMA male antenna or jumper, which makes this assembly a straight in-line extension for an existing antenna run. For best results, treat the feed line as part of the antenna system. Use the shortest practical length, respect the bend radius at each connector, and secure the run so vibration cannot work the couplings loose over time. Panorama Antennas has designed and manufactured antenna systems and RF cable assemblies since 1947, and every CS240 assembly ships with its connectors fitted and tested before it leaves the factory - eliminating the most common failure point in field-built coax.
