I have been looking into playing with drons not the out of box kind to see how far i can fly legally. I see the FAA is cracking down on all of use because a few dump people use them for stupid thing but anyway. I want to add aftermarket antennas on my quads telemetry receiver to compare the difference between a few different brands but i want to make sure i hook the antenna leads up the right way if there is one designated transmitter and one designated receiver or if both antennas do double duty so i wouldnt matter which one you use. Dose that go the same for transmitters with telemetry. All i need is a schematic of a orange telemetry receiver with two antennas and the transmitter two. If not the same schematics for the new Turnigy TGY-i10 and iA10 Receiver. Or the Rfsky version or any other brand. If not i will get the oscilloscope out and figure it out for my self which i dont want to do if someone else has already done it. Thanks

err... "I know that I cannot legally fly beyond Line of Sight LOS, so help me cheat (in a public forum) and let me be another dump(sp) one."

Did I executive summarize that about right?

Spot on! What is more risky than hobbyking receivers and transmitters?

This is just for testing and i plan to do it out in the desert away from everything. I will just use the oscilloscope and figure it out on my own.
The reason i am using hobbyking stuff is because it don't want to mess up my nice jr radios and futaba electronics. Thanks anyways

Programmable radio ICs both receive and transmit.

This is how in-flight telemetry is accomplished.

I wanna know what "dump people" are in relation to R/C flying. LOL

I know they use transceivers but it sounded like some dual antennas were dedicated to transmitting and receiving only. I will hook up my oscilloscope and check the numbers on the internal chips and see whats going on. thanks

One is ground and one is active
No offense, but that is total malarkey.

If you check the technical specs of the WiFi radio IC's, you would see that.

This "wives tale"....aka...."urban malarkey" has been "bandied" about for too long.

The people that claims this have never bothered to look at the tech specs of the radio IC's....and instead just regurgitate internet baloney...which started with "archheli".

It was never true then...and it's still not.

Each and everyone can simply look at the schematics of any WiFi radio IC.

A 2.4Ghz dipole antenna system doesn't act like a 27Mhz antenna.

For a dipole to operate correctly.....both dipole elements are "active".

I challenge anyone on this forum to provide data that shows that ANY dipole element is connected to "ground".

Just examine the WiFi radio IC's schematic.....doesn't anyone do that anymore before making such false pronouncements?????

You might need a spectrum analyzer, rather than an O-scope.

And unless your O-scope...and your spectrum analyzer...is capable of the analysis of RF signals at 2.4 Ghz.....the data is useless.
