How does the Teltonika work out for you - I nearly bought it earlier this year but it doesn't have support for external antennae. I'm just on the edge of 5G coverage and I'm not sure I want to splash out on something which I can't tune for decent reception.

Seems an odd omission for a ruggedised outside modem - the Unifi also seems to not support external antennae.

(I'd also prefer a unifi version just so it fits in the with rest of the networking infra I have in the mökki.)

OTD500 is antenna + router in a single box. There is nothing else needed. I just put it outdoors with a POE cable. Originally, I used it as a backup, but now I have an unlimited SIM, so I use it as a second internet connection.

If you mean the standard routers (like the Rutx50), Teltonika itself sells external enclosures with antennas. https://www.teltonika-networks.com/products/accessories/ante...

Yeah, I know - but an antenna embedded within a small box is going to be much less effective than a big old directional Yagi antenna like https://www.satshop.fi/en/4g/4g-5g/4g-antennas.html

Seems weird to cripple the product by not allowing me to (optionally) disable the internal antenna and instead use and tune an external antenna. And I suspect that is likely to make a difference when you are on the edge of coverage, but you know exactly where the relevant cell tower is, a few km away.

Yeah they're not really putting out new exciting technologies. But this is cheaper than every other equivalent solution on the market for sale today in the USA.
