A mount, I have designed, holds onto the connector itself. This means that mount takes all the load when the antenna is pulled and will not let the antenna pull on the VTX. If the crash is hard enough, and the mount breaks, the VTX will no longer be fixed except by your wires. Better break a small mount rather than your expensive VTX :) The measurements of this one are on the 25mW version. Let me know which versions you want.
