We have bundled 2 of our popular 20cm/8" Ipex to RP-SMA cables together at a discounted price. The pair of cables is ideal if you are using a combo wifi/bluetooth card, like the Intel Centrino 1030, that requires both antennas to be populated for both features to work or just have more then one system to build. Our Hirose U.fl or IPEX to RP-SMA cables fit most Mini PCIe cards including, the Intel Centrino Wireless N series. The blukhead RP-SMA connector makes it easy to mount directly to the case or I/O shield punchout. The connectors are gold plated for optimal signal transfer. The cables measure 20cm or 7.8" in length not including the connectors.
