This is 3db difference, that equates in 40% more range.
In their specs, Frsky is very conservative, distance is also reported as 1.5km only, while tests revealed much more. They report an output power of 60mW, while maximum allowed is 100mW, and FCC report show they are in this range.
Could be important for out of LOS flyers only.

Thanks ! Of course +3db is a good thing. And yes i'm planning to use it for fpv
I saw your reports about range renatoa, very impressive. And if one day i want to go for long range i'll try to add a booster

Booster is unidirectional, will kill telemetry.
Maybe is better in this case to use BEVRC solution. 3 times more costly though

I saw the BEVRC solution, but don't really want to invest on a system which have only one reseller... And if i use a booster it will be with a no-telemetry frsky system.

I have tried mine on the ground with a 1 watt amp, at 3 km it worked without issue, this was on the ground and not elevated so I am picking 1 meter high low passes at 3 km and over 10 km with altitude. Just waiting for the right day to test distance to failsafe

Thanks Mark ! Seems you exactly have the system i'm planning to use
Do you add an attenuator ( and which one) between the Frsky Tx and the booster ??

Hi, I just bought a FrSky module system with telemetry for using with a Turnigy 9x transmitter. is there a mod so I could use the antenna from the 9x connected to the FrSky module? or installing the frsky antenna replacing the original one?

Thanks

Nah, I assumed it was 60 mw output which is well within the limits of my amp, never thought they would have under stated it though. Still I suppose they are cheap enough if the module does fry but I doubt they will. I just started using the 7 channel with ppm out, brought 2 of them, also have the 8 channel telemetery one. They are too cool

Open the original 9x module.
If the 9x module antenna cable is fitted with the same U.FL plug as FrSky, just do a hole in FrSky module, reroute the 9x antenna cable accordingly, and replace the FrSky antenna cable in the board plug with the 9x cable.
If 9X module antenna cable is soldered... then we have a problem...

Hi Renatoa, I ordered from Phlatkits.co.nz in New Zealand here (kneedrag on Rcgroups) he said they would take a week for delivery and emailed me 2 days later and said they had arrived too cool.
Makes hooking up the dosd+ a breeze. Be keen to get the firmware update for the telemetery receiver too.

I'm pretty sure the antenna cable is soldered on the board of the Turnigy 9c Tx.
I've seen a thread on hobbyking forum's with pics...

but would it be possible to buy a connector and soder it to the end of the cable from the original turnigy module antenna and then reroute it outside the radio back case and connect it to the FrSky module?? does that influence the transmission? also are all the antennas pretty much the same, or they may differ??
Sorry about all this questions but i don't want to do anything without being 100% sure that it will work..

I think the easiest way is to add this antenna http://www.hobbyking.com/hobbyking/s...idproduct=9204
You just have to glue it in the same place the original Turnigy antenna was,the cable goes inside the transmitter, then make a hole in the transmitter case to get the connector screw in the module.
