simple is check range of transmitter before and after fitting

another simple way is attach to a wifi router - your wifi network range will be around double

you cannot quantify the output without special equipment

High end equipments like spectrometer are not 'fancy', but certainly a luxury for a few with deep pockets. Read the first post, and check if your Bluetooth connectivity is getting knocked off. If yes, then you have a good signal strength.

Using a booster is against the rules and regulation of India WPC.

Technically speaking, you should not alter your radio's. Risk is at onus of the owner of such equipment. Period.

got my radio signal booster 2000mw today
mounted it to my radio it works perfect

but as mentioned in earlier post it didnt knocked out my laptop to mobile Bluetooth data transfer link ??
i guess i have to try it with wireless head set??


i have one question thouh:-   my radio is still working without powering on the booster still i am able to receive the signal on receiver why is that  Huh? is it normal working or something is wrong??  note:- i have removed the stock antenna completely from flysky module and soldered the coex cable to radio booster

see the pictures

Any bdy know the exact range you get if you install 2.4ghz wifi booster on trex...and am confused..as i already have djt module and for long range which one is better adding booster to djt or get ezuhf dragonlink or any other long range system

The radio still works with booster switched off for good range. It's normal.

Range you achieve will be anything between double to manyfold increase based on you other setup and connected accessories. Boost in range is not a fixed arthemetical multiplication factor. It depends on many other factor of setup and how you use it.

Hope for the best! I dropped my plan of buying ezuhf..will go with 2watt booster and patch antenna lets see how it will work,and seen some people on forms who added booster to djt module and achived nearly 20km+,as they ppl have long range fpv airplanes like sky hunter to test the range...searching for sky hunter 1800mm size

Adding a wifi booster will surely increase your range... but there are a few points to consider...

1.) Decide how will you power the booster as it consumes significant amount of energy.
2.) What antennas you plan to use ? If using a patch(directional) it will boost your range quite a bit but will add to the complexity of pointing the tx towards the model all the time. The farther the model goes, the narrower the beam funnel becomes, so an antenna tracker might be useful in this case. However, if you use Omnidirectional antennas, the efficiency of those are not that great and you may not get the desired range as expected.
3.) Multipathing can cause issues and there could be phase outs at the receiver end. (2.4 Ghz is more susceptible to it)
4.) Last but not the least, adding a booster would be illegal as per WPA. You may even void the warranty on the tx.

I still feel that a LRS on 433 MHz is more practical in this case. 433 would have more penetrating power and hence you will be in control of your aircraft even if it flies behind trees or other obstructions. It will consume much less power compared to a booster and hence, can be powered from the tx battery itself. Many LRS systems offer dual power modes. Low power (typically 200 mW) and high power (500 mW)
The sensitivity of LRS receivers is much higher than traditional 2.4GHz rx.
You can use Omni directional antennas with 433 MHz systems and they provide adequate range. You save on the antenna tracker setup.

The 433 LRS system is expensive compared to adding a booster but a much reliable setup for long ranges however it may not be bi-directional (if using old systems like "dragon link") and hence may not support telemetry. If you use data modems which operate on 433 MHz band then you get telemetry but they suffer from low baud rates.

At the end, the choice is yours. Booster is cheaper and would work with existing systems but will induce the hassle of tracking the aircraft all the time. A true 433 LRS would be more robust and reliable at an expense and may further add legality issues.

Retreat, Hell!



... If you use data modems which operate on 433 MHz band then you get telemetry but they suffer from low baud rates...

I've been able to achieve 7 ms per packet (Tx to Rx) and 10 ms per packet for telemetry at 19200 baud using 433 MHz long range modems from DORJI. It's still slow for fpv racing  but much better than the traditional 50 Hz systems for fpv flying. 

The serial protocols like SBUS and SUMD took 2-3 ms more.

I have fst6 radio and its range is less

So members are requested to intimate link where hardware to increase the range of transmitter is available and method to install on fst6 radio

Just a novice here. But with all the restrictions about flying, altitude, line of sight, fpv  ... do we need the extra power drawing signal amps.
There are some options like this  Giggle
