Desktop television antenna "Volga" (ATN-6.2) has been produced since 1981 by the Saratov Aggregate Plant. ,8caa42f5a9df53968033bf99609e44f6 The antenna is made according to the scheme of a shortened non-moving symmetric meter wave vibrator, in which the vibrator is configured on any of the 12 channels. ,8caa42f5a9df53968033bf99609e44f6 The vibrator shoulders are attached to the base with flexible metal hoses. ,8caa42f5a9df53968033bf99609e44f6 This method allows you to independently tilt the shoulders of the vibrator in different directions, which facilitates the orientation of the antenna. ,8caa42f5a9df53968033bf99609e44f6 Each arm of the vibrator is made of several conductors (rods or tubes with a diameter of 8 mm), connected in parallel in order to reduce the magnitude of the wave impedance of the vibrator and expand the band of operating frequencies. ,8caa42f5a9df53968033bf99609e44f6 The length of each arm of the vibrator, including the flexible hose, is 745 mm, i.e. ,8caa42f5a9df53968033bf99609e44f6 close to a quarter of the wavelength of channel 5. ,8caa42f5a9df53968033bf99609e44f6 The vibrator shoulder width in the upper part is 120 mm. ,8caa42f5a9df53968033bf99609e44f6 Switching of channels is carried out with the help of a switch to two positions (channels 1-2 and 3-12), switching on or off compensating coils. ,8caa42f5a9df53968033bf99609e44f6 ,null,ru,null,null,null,null
