TX/RX KitSet consists of TX and RX
Modules and Interface PCBs, Modules and PCBs are assembled and fully tested.
Assembly involves soldering Modules to PCBs (or via wires) and enclosure in a
housing, no tuning or alignment required. All components are fitted to PCBs
including Pre-Programmed Microcontrollers, Inductors, Sockets, Switches, ICs,
Capacitors, etc., connection and operating notes are supplied. A simple 1/4 wave
antenna consisting of a straight piece of ~ 35 mm x 0.9 mm wire, inserted into
SMA Antenna socket and retained with Heat Shrink Tubing is adequate for short
range applications.
Video Transmitters may be
legally used without a licence within the *LIPD 2400 ~ 2463 MHz Band and 10 mW *EIRP
limit.
RANGE

surroundings, obstructions, structures, antenna gain, other transmitters, EMI
and RFI in the vicinity.

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 transmitter output from 10 mW to ~
20 mW, 5 dBi ~ 33 mW, 8 dBi ~ 66 mW, 12 dBi ~ 160 mW, 15 dBi ~ 320 mW, 18
dBi ~ 640 mW, 21 dBi ~ 1280 mW, 24 dBi ~ 2560 mW.
