Smart controller antenna question

[Brendan688]

Hello all, I’m looking for a V2 smart controller (posted in the classifieds) but wanted some opinions on one that I saw. The listing says it has one original antenna and one aftermarket antenna. The pictures show they are different. Doesn’t seem like a good idea to have different antennas or maybe it’s fine? I’m debating if I get that one if I should by a new set so they are the same. Anyone have any knowledge/opinions on that? Seems weird to have different antennas on it. Thanks for any input.
