FIELD: radio engineering.
SUBSTANCE: wireless field device (100) consists in housing (102) that has processor (110), located in housing. Power module (112) can also be located in the housing (102) and can be connected with processor (110). Wireless connection module (104) is connected to processor and performed with the possibility of communication with the use of radio-frequency signals. Antenna (106, 202) is connected with wireless connection module (104). Radome (116), mounted at the housing (102), is made of polymer material. The radome (116) has a chamber (124) inside, where there is antenna (106, 202), and has a surface that contacts the housing for prevention of radome spontaneous turning in relation to the housing.
EFFECT: security increase.
