  • Page 6 History Guglielmo Marconi Inventor of the “wireless” Receiver-Transmitter 1873 – James Clerk Maxwell published his Treatise on Electricity and Magnetism, setting forth the basic theory of electromagnetic wave propagation. 1888 - Heinrich Rudolph Hertz detected the first radio waves. He demonstrated that disturbances generated by a spark coil showed the characteristics of Maxwell’s radio waves.
  • Page 7 1917 - The U.S. Army started using radios as they entered WWI. 1924 - Edward Appleton proved that the blanket of electrically charged (Ionized) particles in the earth’s atmosphere (Ionosphere) was capable of reflecting radio waves. In the late 1920’s, Scientists applied this theory and developed ways to measure and predict the refractive properties of the ionosphere.
  • Page 8 Antennas • Transmit and/or receive electromagnetic waves • Varies in shape and size depending on the type of wave it transmits/receives An antenna is a passive device, which does not offer any added power to the signal. Instead, an antenna simply redirects the energy it receives from the transmitter.
  • Page 9: Antenna Characteristics

    Antenna Characteristics Gain is a measure of increase in power and is the amount of increase in energy that an antenna adds to a radio frequency (RF) signal. Direction is the shape of the transmission pattern. As the gain of a directional antenna increases, the angle of radiation usually decreases.

  • Page 54 Extending the Tripod • Loosen the adjustment knob on each of the 3 telescoping legs by gripping with one hand the knurled area immediately below each knob and with the other hand rotating the knob counterclockwise about ¾ turn. • After all three adjustment knobs have been loosened, grip the Tripod with both hands by two legs above the turn knobs and lift until the legs fully deploy.
  • Page 55 BlueSky Mast Setup (5) Level the Tripod: • Locate the two bubble levels on the top of the Tripod just below the knurled section of the Tri-Collar. The perpendicular positioning of two bubble levels assures easy, accurate leveling. • When the air bubbles in both levels are centered between the level marks at the middle of each bubble level, the Tripod is level.
