Wow that’s a tiny GPS antenna! This passive antenna is only 15mm x 15mm x 6.8mm in size, with a 50mm long uFL cable. Great for when you want to keep things small…
Hi Josh
Probably not very well. The frequencies are very different. An antenna is a physical thing, the length will determine the frequency of resonance so the GPS antenna will be too short for effective reception at 900 plus MHz and definitely too short for 433MHz.

Hi Josh
Sorry I did not notice the GPS seems to be separate to the lower frequency bits (LoRa).
You are right in that Lilygo don’t provide much detail on that GPS bit. You will have to try and decipher the numbers printed on that GPS and find out if it supports an active or passive antenna. I believe some GPS units need active (powered) antennas. The one you linked (from Core) is passive.
They also don’t show the other side of the board so you will need to check the connector type also. If you haven’t got one in your hand I am not sure how you are going to do that if Lilygo are not communicating.
