loaded antenna การใช้

• Upon reaching the ocean surface, the outer casing and parachute break away from the SLDMB, and the spring-loaded antenna deploys.
• But the engineers worry that they could encounter a similar problem when they release a spring-loaded antenna soon after the craft reaches its final orbit.
• The company s primary focus is on designing and manufacturing patented dielectrically loaded antenna technology, this technology is specifically aimed at hand held devices which are mostly used close to human bodies.
• Although like other electrically short antennas the rubber ducky has poorer performance ( less gain ) than a quarter-wave whip, it has somewhat better performance than an equal length base loaded antenna.
• The inductive reactance of the coil is equal and opposite to, and cancels, the capacitive reactance of the antenna, so the loaded antenna presents a pure resistance to the transmission line, preventing energy from being reflected.
• The unit's equipment consists of a 10.6 kW AM band broadcast radio transmitter; a broadcast studio van; antenna tuner; two antennas ( a pneumatically raised top-loaded antenna mast and a wire helium balloon antenna ); and a 30 kW generator that provides power to the system.
