BNC - is the connector name/type used for the TX and Booster for my LRS, same connector is used on
Ethernet systems.
Booster - is an amplifier that will take radio signals and boost them up to a more powerful level.
LNA - Low Noise Amplifier is used in receivers as the front end stage, they improve the sensitivity and
therefore also the range
Diversity - is often a double antenna and/or double receiver system with auto switching to the best signal,
this improves the useable range allot
GPS - often we use a GPS receiver on planes to feed speed, position, and height information to OSD
systems.
OSD - On Screen Display, will overlay interesting information to a live video signal.
Logger - will record data or measurements for playback / view later, some OSD systems can log some
information’s too.
Modem - Modulator Demodulator, encode data into sound, and back again, can use audio line in a wireless
video system to transfer data like GPS positions
Head Tracker - a unit mounted on a person’s head, will then control remote located servos so a remote
camera follow head movements, gives Virtual Reality experience to FPV.
FPV - First Person View, like pilot view out the front window.
UAV - Unmanned Aerial Vehicle, a UAV is a fully computer guided plane, not a radio controlled plane,
if RC'ed it is an FPV or just a normal RC plane
Trainer - Most advanced RC units have trainer connectors with PPM in/out so they can be connected via a
cable to a student RC unit.
Student - Most advanced RC units have trainer connectors that can be configured to output PPM signals for
a PC simulator or trainer RC unit or LRS.
Patch - A patch antenna is a directional antenna that will when pointed to a plane improve the range
Yagi - A Yagi antenna is a directional antenna that will when pointed to a plane improve the range
Dish - A Dish antenna is a directional antenna with highest possible gain, will when pointed to a plane
improve the range
Gain - antenna gain is often named in db, more db more gain, and also a more narrow beam, so pointing
correctly is harder with high gain.
RF - Radio Frequency, any frequency that is not directly hear able audio
RF module - often a plug in box or module or printed circuit board that can be changed/added in RC units,
normally a transmitter
BEC - Battery Eliminator Circuit, is a 5V-6V regulator often linear type that makes supply for RC RX and
