In Australia Video Transmitters may be legally used without a licence within the *LIPD 2400 ~ 2463 MHz Band and 10 mW *EIRP limit.


Depends on Surroundings, Obstructions, other Transmitters (2.4 GHz Cordless Phones, Wireless LAN, etc), Antenna Alignment,  Electromagnetic & Radio Frequency interference in the vicinity.

In ideal, clear, Line-of-Sight conditions with Vertical 3 dBi Whip antenna on TX

Vertical 3 dBi Whip antenna on Receiver up to ~ 100 m.

Correctly matched and aligned 18 dBi antenna on Receiver up to ~ 600 m.

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 Receiver and/or Transmitter (in Australia TX may only be fitted with 3 dBi antenna). For maximum signal transfer TX and RX antennas should be the same polarity, that is both oriented Vertically or Horizontally.

Parabolic Yagi & Flat 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 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)
