A wireless field device or an adapter for converting a wired field device to a wireless field device includes a housing, a first connector on the housing, and a removable antenna module that includes an antenna, a second connector coupleable and uncoupleable with the first connector, and a radome that houses the antenna and fits on the second connector. The radome is made of a static dissipative material that dissipates static buildup without sparking when coupling or uncoupling the connectors, enabling the antenna to be removed or replaced while the field wireless field device is located in a hazardous (classified) location.
