aligned 24 dBi antenna on RX and 3 dBi antenna on TX up to ~ 1 000
Correctly matched and
aligned 24 dBi antenna on TX & RX up to ~ 2 000 metres

Due to the nature of Radio
Signals results are unpredictable (in the same manner as Mobile /
Cellular Telephones) 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
Range and Signal to
Noise Ratio (SNR) may be improved by increasing gain of antenna on
Transmitter &/or Receiver. For maximum signal transfer TX and RX
antennas should be the same polarity, that is both oriented
Vertically or Horizontally.

Antenna Gain... what
does it mean ??? a simplified explanation
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
The maximum allowed
2.4 GHz LIPD Video Transmitter output power is 10 milliwatts (mW) EIRP
(in Australia), increasing transmitter output is illegal and therefore
not an option.
Increasing the gain
of the receiver 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 10 mW
transmitter to ~ 20 mW. (5 dBi to ~ 33 mW) ( 8 dBi to ~ 66 mW) (12 dBi
to ~ 160 mW) (15 dBi to ~ 320 mW) (18 dBi to ~ 640 mW)
