4G hat compatibility with different antenna?

Raspberry Pi Network HATs 3G/4G&LTE Base HAT
1

Hello, I got gifted a 4G LTE hat and a EC25 module, I did not however get given any antennas. I have read on the sixfab website that I need the two linked below but incl shipping to UK this is almost 40 euros? do you know if I can use any other antennas? I also got given some adaptors that connect the u.FL to a larger jack that is used for computer wifi antennas, can something like that be used or must I use the sixfab ones? also can I use any normal UK 3G / 4G sim?

I’m trying to make a mini security system based on a raspberry pi and I need a cellular connection, no GPS or anything just 3G or 4G

Help would be greatly appreciated, Thank you in advance

Hi,

We recommend using Sixfab LTE antennas that you mentioned. If you share the different antenna you will use, we can say you if it is compatible or not. You can use a normal UK 3G/4G SIM, but don’t forget to set up the APN.
