Where does one buy the LTE pack for Turris Omnia?

I’ve seen a couple of places mentioning the LTE pack for Turris omnia, but I can’t find a single place that sells them (I’m based in the UK). Is the LTE pack available to be purchased or was it part of the initial Indiegogo campain? I could potentially purchase the parts separately, but there doesn’t seem to be a way to purchase extra antennas.

LTE pack was part of the initial campaign.

… which means you might still be able to find someone selling it, e.g. OMNIA 2G for sale /200€/ SOLD partially

If you do not want to build it by yourself, I could build it for you.
