Easy tutorial on how to upgrade your standard quadcopter transmitter by installing a high gain antenna. Watch the video to find out how to do it.

Step 1: Take Transmitter Apart to Expose Antenna Port

There are 4 screws on the outside of the transmitter and 10 on the inside holding the green board down. Take these off and then unplug the big white cable to allow for easier movement.

Step 2: Un-solder Old Antenna

un-solder the old antenna but remember which dot the ground was connected to and which dot the main wire was connected to.

Step 3: Connect High Gain Antenna to Rp-sma Cable and Cut Off Other End

connect the antennna to one end of your rp-sma cable, then take some scissors and cut off the other end which is where we will do our soldering

Step 4: Strip Wire and Gather the Ground

Strip the wire twice to expose the ground and also the inner wire. Then take your fingers and roll them along the ground to roll the ground up into a solder-able wire.

Step 5: Solder on New Antenna

Solder on both parts of the rp-sma cable making sure to put the ground where the old ground was and the inner wire where the old inner wire was.

Step 6: Cut Hole in Transmitter Large Enough for Antenna to Go Through and Glue Antenna Into Place

Cut a hole in the transmitter. I used a band saw but i guess you can use some other tools to get the job done. Then just add a whole bunch of hot glue and you should be good.

Step 7: Watch the Video If You Are Unsure About Anything

If words cant explain it well enough, watch the video.

<p>hi, i have the same cable, but i dunno the length, do i have to cut it as the stock one, or just leave it and solder it on as is ?</p>
<p>It'd be great if this instructable had step by step photos and instructions without just relying on the video.</p>
<p>I've always wanted to get into quadcopters. They look like so much fun! </p>
