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. http://www.ebay.nl/itm/FPV-5-8G-Clover- ... 43c878c495 http://www.ebay.nl/itm/1-Pair-5-8G-SMA- ... 43c87790d3 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.
