    I know there are some ready-to-buy alternatives around, but i would like to buy a cheaper version and modify it to work for the phantom.
    Now, if we all work together we might be able to get something going here wich might be alot less expensive.

    Now, without much knowledge accept replacing my router's antenna, i know that there are different kinds of antenna's, to get the signal into different directions.

    To find some stuff on ebay first, to see if they can fit our project.

    We probaly need to find out if these fit the specifications of our controller, then know how much gain they add up, then know how to connect these. Because in general it remains plastic with a wire.

    For the controller, there is very little (if any) benefit in using CP antennas. Also, as your choices somewhat point out, if you change the controller (TX) side to CP, you really should also change the Phantom (RX) side. It is not required, but if you do not, you will suffer a 3db loss (essentially like cutting your power in half.) BTW, there are two antennas on the Phantom side, again, no need to change both, just will not be optimal. Also, just to note, changing the RX antennas on the Phantom can be tricky.

    For the controller, the best options are either a larger whip than the stock EX:

    Or even better is a patch. Ex (I get over three miles with one like this):

    Using any antenna (other than stock) on the controller requires adding a pigtail (search for instructions.)
