Antenna Gain... what does it mean ??? a simplified explanation

Received signal strength from an antenna with 3 dBi gain will be double that from an antenna that has 0 dBi gain, received signal strength from a 6 dBi will be double that from a 3 dBi and so on... An increase in antenna gain of 3 dBi is approximately equal to doubling the transmitter output, received signal strength or range can be increased by raising antenna gain or transmitter output. Range can be doubled by either increasing antenna gain by 6 dBi or quadrupling the transmitter output power.

Increasing the gain of the Receiver or Transmitter Antenna is an alternative to increasing transmitter output.
In very simple terms: increasing antenna gain from 0 dBi to 3 dBi is equivalent to raising the output power of a 1 Watt transmitter to ~ 2 Watts (5 dBi to ~ 3.3 Watts) (12 dBi to ~ 16 Watts) (15 dBi to ~ 32 Watts) (18 dBi to ~ 64 Watts) (24 dBi to ~128 Watts)

Due to the nature of Radio Signals results are unpredictable signals reflected from surrounding objects arriving at Receiver antenna may Add-to or Subtract-from the direct signal from Transmitter. Directional antennas may reduce affect of reflected signals.

Range and Signal to Noise Ratio (SNR) may be improved by increasing Antenna Gain on Receiver &/or Transmitter. For maximum signal transfer TX and RX antennas should be the same polarity, that is both oriented Vertically or Horizontally.

Parabolic, Yagi & Flat Panel are directional antennas. Whip antennas when used vertically are for most practical purposes omni or non directional.

To maximise 'Range' minimise the length of Coax Cable between Antenna and Transmitter and Receiver.
