Double the range of your Tx's by adding a 5dbi antenna...it works!

You should be careful doing this. You can exceed the maximum legal EIRP output doing this, which can result in some really big fines from the FCC or their equivalent depending on where you are.

It's just changing the antenna... no amplifier.

My legal limit is what the radio have 100mw. NOT going to change nothing in that department, mainley because it's illegal and i don't even know how to, but don't care either....

And it's not really needed, This is plenty suficient for RC line of sight! Those FPV "guru's" are what you are talking about... this is simply changing the antenna!

Also the antenna is selled on any computer stores...

I made the video of mine...

Changing the antenna changes the EIRP, and it's definitely covered by the regulations. If your high gain antenna pushes you over the limit, you need to reduce transmit power in the radio.

Ok, i understand. There is also a switch on radio & rx from France to Europe.
France is lower.

Thanks for the advice!
