Depends on Surroundings,
Obstructions, other Transmitters (2.4 GHz Cordless Phones, Wireless LAN, etc),
Antenna Alignment, Electromagnetic & Radio Frequency interference in the
vicinity. This device may be affected by and may affect other devices that
operate on or near the same frequency causing minor to severe interference.
In ideal, clear, Line-of-Sight
conditions

Receiver up to ~ 100 metres.
Correctly matched and aligned 24
dBi antenna on RX and 3 dBi antenna on TX up to ~ 1 000 metres.
Correctly matched and aligned 24
dBi antenna on TX & RX up to ~ 2 000 metres
Higher than 3 dB on TX not allowed in Australia.
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 reflected signals.
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.

length of Coax Cable between Antenna and TX/RX.
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.
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)
* LIPD = Low Interference
Potential Devices. * EIRP = Equivalent Isotropically Radiated Power.
