TX/RX KitSet V2
consists of TX and RX Modules and
Interface PCBs, Modules and PCBs are assembled and fully tested. Assembly
involves soldering Antenna Coax Cable to PCB Track in Module, plugging Module
into PCB or connecting to PCBs via wires and enclosure in a housing, no tuning
or alignment required. All components are fitted to PCBs including 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
wire is adequate for short range applications. For Compact applications the
Transmitter PCB may be dispensed with and connections made directly to pins,
Channel selection may be hard wired. No Circuits or Data available.
Video Transmitters may be legally used without
a licence within the *LIPD 2400 ~ 2463 MHz Band and 10 mW *EIRP limit.

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

* EIRP = Equivalent Isotropically Radiated Power
