Sometimes, the Rx (radio receiver) and/or VTX (video transmitter) antenna may be damaged, tip broken off, or chopped off by the propellers. Unfortunately, replacement antennas are not something we sell separately, as it is not generally a user serviceable part because of the delicate soldering required. Such repairs/modifications are not recommended, and will NOT have support or warranty coverage. Instead, replacement AIO (all-in-one) boards (i.e. TinyHawk series), VTX, and Rx are available for purchase.

If you are comfortable with soldering small connections and are willing to take the risk:

(Usually thinner gray section with a shiny/clear tip.)

If there is enough coax cable left, you can peel back and trim away the outer insulation layer along with the grounded braided sleeve. Just leave 31.23mm of the inner insulation with the active signal wire inside. Like here: https://oscarliang.com/repair-2-4ghz-antenna-rx/ 

If not enough coax cable left, generic 2.4GHz antennas are available many places online. Some may have a connector (like in the linked article above), which you can just cut off. Then you'd separate out the layers again, this time soldering the braided sleeve to the larger ground pads on the sides, and solder the center/signal wire to the tiny signal pad. Please reference how your stock antenna was attached.

(Usually thicker gold/clear or black section with a wide black tube and shiny/clear tip.)

Generic 5.8GHz antennas are available many places online. Some may have a connector (like in the linked article above), which you can just cut off. For example, you could try the EMax antenna for the Hawk 5 (https://emax-usa.com/f4-magnum-tower-parts-5-8g-dipole-whip-antenna.html ).Then you'd separate out the layers again, this time soldering the braided sleeve to the larger ground pads on the sides, and solder the center/signal wire to the tiny signal pad.
