 After mounting the antenna bracket, position the antenna on the bracket, and tighten the nut.
+If it's absolutely necessary to use an extension cable for the antenna, keep it as short as possible and use high quality coax cable. Note that the losses in extension cables are significant. For example, 6m (20ft) of RG58 cable attenuates roughly 50% of the signal.
