This is the cheapest way to replace that good ole reliable antenna that you totally didn't break in a crash it just somehow broke on its own! These antennas are reinforced right here at Tiny Whoop Headquarters on the tiny connection between the top and bottom of the lobes, the exact part I always reinforce in all of my builds. These are the lightest antennas I've found.
The best part about these replacement antennas is that they're relatively simple to install. The ground (earth) and signal are perfectly spaced so a very simple solder, as in this pic below.
