3. Point Configuration A Loop Antenna is simply insulated electrical wire with a terminating resistor on the side of the loop furthest from the connection to the Decoder They are buried beneath the surface of the track and are 24 inches approx 60 cm wide and can be of varying length to cover the width of the track See fig 1 4 A track width greater than 100 ft approx 30m can be covered with a single Loop Antenna but it depends on the track type dirt versus paved burial depth of the loop and the track environment iron content in the soil or RF interference Itis not desirable to make the Loop Antenna any longer than necessary since it will reduce the performance of the system The ends of the Loop Antenna connect to the balun The balun is a device that connects the Loop Antenna to a RG58 50 ohm coax cable The balun device matches the impedance between the Loop Antenna section and the coax It is necessary to have a balun device for optimal performance Without it the impedance mismatches can result in reduced detection height and possibly intermittent and unpredictable behavior m Terminating Resistor Can be greater than 100 feet 30m gt balun Fig 1 3 Loop Antenna Dimensions 4 2 Installation and Usage 2 0 General Notes The first step in an installation is to carefully plan where each piece of the system will reside The plan must take into account the limitations of the system Some of these li
