Thanks man is there a specific brand or type? When I Google it I get these kind of big ones, would I just attach to the end or open it and do surgery? 🙏 10PCS 100mm 2.4G Receiver Antenna for Frsky X4R X4RSB XM XM+ R-XSR Replacement Antenna IPEX 4 V4 Port S6R S8R F30 F3OP F40 F4OP https://www.amazon.com/dp/B07JFZDYVS/ref=cm_sw_r_awdo_1W5QFCX99PY92MNMSZ72
You can buy replacement antennas from Amazon or some other FPV vendor.

Yes just pop it in.
I mean it's a diversity antenna, so you could fly with just the one antenna. That's what diversity is for!
But yes you COULD cut the antenna in half, and reattach the cut piece to your other u.fl. However, soldering up to that other u.fl is going to be super hard to do so it's probably not worth your time.
The antenna theory is correct though. Antennas are just pieces of wire cut to specific lengths to resonate certain frequencies. You could take any old piece of wire and solder it to the u.fl center pin and as long as its cut to the right length it will work.
But you don't need to order from bang good either. check amazon
Just replace it.
These are what you'll need.

I use these antennas for them:

The antennas can be hot-glued to the board (right under the wired LAN port).
