LoraWan Gateway

Hi Guys,
I’m keen to get a LowraWan gateway, unfortunately, there isn’t one in my area of Sydney. What do you recommend? I can’t really afford the full-on setup, with $1K setup cost.

Is Core’s RPi $225 offering suitable? can an outdoor antenna be connected to it? Or is there a suitable entry-level alternative?

I have developed a node on a Lopy4 and tested it with the TTN via a Lopy4 nano gateway as proof of concept, but need to establish a permanent gateway (Lopy4 is not suitable).

Grateful for your advice.
