    Section 2 Microwave Path Engineering Basics TRACER 4102/4202 System Manual most applications, 20 to 30 dB of fade margin should ensure a reliable link. The following sections further discuss the necessary power calculations and their components. RECEIVER POWER The viability of a particular microwave path is determined by the power of the transmitted microwave signal, the transmit and receive antenna gain, distance, and accumulated system losses (such as RF coaxial cable losses and path loss).

  • Page 17: Antenna Gain

    6 dBi. At 2.4 GHz (TRACER 4102), the 1-watt maximum transmitter power must be reduced by 1 dB for every 3 dB of antenna gain over 6 dBi. Since the TRACER 4102 maximum transmit power is 100 milliwatts, only antennas with gains above 36 dBi (12-foot diameter parabolic dishes) require any reduction in transmit power.

  • Page 18: Carrier Wavelength (L)

    Coaxial cable is required to attach the TRACER 4102/4202 to the antenna. The length of the cable varies from a few feet to hundreds of feet, depending upon your application and the proximity of the TRACER 4102/4202 to the antenna. Various grades of coaxial cable will work sufficiently well for connecting the TRACER 4102/4202 unit to the antenna.
