Newbie Questions about Antennas (sh.itjust.works)

Like the title mentions I am new to Meshtastic and would like to buy a T-Deck Plus with an external antenna from Lilygo (as I heard the internal one is not that good). Does anyone know if an antenna like this would work/make sense with that device? What antennas do you use? Thanks in advance.

I'm also not that experienced with Meshtastic, or radio communication in general, but I think you should consider another antenna for a few reasons.

The size is a bit small. At least it looks like it from the pictures. The description says 36 cm, but that's including the connection cable which you won't use on your T-Deck, right? It's probably incorrect to say that a longer antenna is always better, but I've solved issues with one of my Meshtastic devices by increasing the size of the antenna a few times.
It's made of fiberglass. There are flexible antennas which I think would fit better with the portable nature of your T-Deck. I couldn't find one on the website you linked, unfortunately, but just searching for "868MHz Antenna" on Amazon/Aliexpress should give you some results like this:
The price is quite steep. 45€ vs ~10€ for other options.
And least important point, it's white, but your T-Deck is dark gray I assume?
