NOTE
Distance and Antenna gain values are required when calculating EIRP. Effec
-
tive Isotropic Radiated Power (EIRP) refers to the amount of power that a the
-
oretical isotropic antenna (which evenly distributes power in all directions)
would emit to produce the peak power density observed in the direction of
maximum antenna gain. EIRP can take into account the losses in transmission
line and connectors and includes the gain of the antenna. The EIRP is often
stated in terms of decibels over a reference power emitted by an isotropic radi
-
ator with equivalent signal strength. The EIRP allows comparisons between
different emitters regardless of type, size or form. From the EIRP, and with
knowledge of a real antenna's gain, it is possible to calculate real power and
field strength values.
Formula to calculate: EIRP = Tx RF Power (dBm)+GA (dB) - FL (dB)
Tx RF Power refers to RF power measured at RF connector of the unit
GA refers to Gain Antenna
FL refers to Feeder loss (cable loss of any other loss occurred)
You can tap to switch to Channel Power or EIRP under the chart in the table,
and it will show the automatically calculated value.
