The antenna gain in dBi: Enter 2.2 for dipoles; add 2.2 for antennas rated in dBd. The distance to the area of interest: From the centre of …
WebbTo estimate your average power, first start with your Peak Envelope Power (PEP). Multiply that by the duty factor for the mode you are using, then by the maximum percentage of time you expect to operate within the averaging period.. For example, if you operate a 1500 watt PEP SSB (phone) station that is on for 10 minutes, off for 10 minutes and on again … WebbYou should also consider feedline loss in calculating your average power at the antenna. If you wish to estimate the power density at a point below the main lobe of a directional antenna and if the antenna's vertical pattern is known, recalculate using the antenna's gain in the relevant direction.
