DescriptionF Male – SMA Female Adapter Adapt TV type coax cable to 3G/4G cables and patch leads.TV coax is 75 ohm as opposed to the 50Ω impedance rating of 3G/4G antenna systems. Using TV type RG6 or RG11 with mobile broadband devices creates an impedance mismatch that can result in high VSWR and thus an additional signal loss of 3dB or more. For this reason we do not recommend nor supply 75Ω coax. However we do get many requests from customers and TV antenna installers for connectors to suit the TV coax.If it is expected that the signal strength will be quite high once the antenna is installed and your building already has 75Ω coax run from an obsolete satellite dish ot TV antenna, you may wish to re-use that coax with a 3G/4G antenna. Its not the best way to go, but can often be sufficient.Converts an SMA Coax Connector to F type.
