TBS Unify Pro HV 5.8GHZ VTX - Manual V2

Good practices
We have compiled a list of all of practices which have been tried and tested in countless environments and
situations by the TBS crew and other experienced FPV pilots.
Follow these simple rules, even if rumors on the internet suggest otherwise, and you will have success in
FPV.
Start with the bare essentials and add equipment one step at a time, after each new equipment
was added to proper range- and stress tests.
Do not fly with a video system that is capable of outperforming your R/C system in terms of range.
Do not fly with a R/C frequency higher than the video frequency (e.g. 2.4GHz R/C, 900MHz video).
Monitor the vitals of your plane (R/C link and battery). Flying with a digital R/C link without RSSI is
dangerous.
Do not use 2.4GHz R/C unless you fly well within its range limits, in noise-free environments and
always within LOS. Since this is most likely never the case, it is recommended to not use 2.4GHz
R/C systems for longer range FPV.
Do not fly at the limits of video, if you see noise in your picture, turn around and buy a higher-gain
receiver antenna before going out further.
Shielded wires or twisted cables only, anything else picks up RF noise and can cause problems.
When using powerful R/C transmitters, make sure your groundstation equipment is properly
shielded.
Adding Return-To-Home (RTH) to an unreliable system does not increase the chances of getting
your plane back. Work on making your system reliable without RTH first, then add RTH as an
additional safety measure if you must.
Avoid powering the VTx directly from battery, step-up or step-down the voltage and provide a
constant level of power to your VTx. Make sure your VTx runs until your battery dies.
Do not power your camera directly unless it works along the complete voltage range of your
battery. Step-up or step-down the voltage and provide a constant level of power to your camera.
Make sure your camera runs until your battery dies.
A single battery system is safer than using two dedicated batteries for R/C and FPV. Two batteries
in parallel even further mitigate sources of failure.
For maximum video range and “law compatibility”, use 2.4GHz video with high-gain antennas.
When flying with R/C buddies that fly on 2.4GHz, or when flying in cities, it is perfectly possible to
use 2.4GHz video provided you stick to the channels that do not lie in their band (CH5 to CH8 for
Lawmate systems, available from TBS).
Do not use diversity video receivers as a replacement for pointing your antennas, diversity should
be used to mitigate polarization issues.
Improving the antenna gain on the receiver end is better than increasing the output power (except
