Like title says, what are the specs for the included antenna in the mm8108 ekh19 kit?
Thanks in advance!

The website isn’t really working for me. But these antennas are Pulse Larsen W1063. See [https://productfinder.pulseeng.com/product/W1063](https://productfinder.pulseeng.com/product/W1063)

Thanks for the quick answer. That’s interesting, the minimum frequency is listed as **868 MHz** , but in when I run the morse\_cli tool on the included gateway, the output says:
> Current RF frequency (Hz): 864000000
Could that be a problem? When I ran the web UI wizard for the gateway, I configured it for the EU, so I guess parameters should be set according to regulations (mostly).

868 MHz may just be the advertised description. In the datasheet they provide all measurements and charts are conducted from 863 MHz, with no significant difference in gain, VSWR or efficiency in that range.

Ah okay, I see, that makes sense. Thanks!
