Got a client who Vodafone have just moved to fixed wireless and supplied a TP-Link Deco X80, they are (just) within the 5G coverage area, but aren't connecting to 5G, and speeds are very poor - under 10mbps most of the time. Customer is saying it's worse than ADSL.

I've not seen these Deco devices in the flesh, but it looks like it has 2x RP-SMA connectors - can't seem to find a high res image of the device, and the manual isn't tons of help other than saying it has '2x external antenna interface'.

Wondering what would be a recommended antenna to try and pickup a 5G signal - @coffeebaron if you had a sec to let me know your thoughts I'd be most appreciative. :)

Only thing I'm concerned about is the Deco connecting to the 'wrong' tower - is there a way to force it to 5G only?

Thanks very much!

You may need 2x of these: https://www.gowifi.co.nz/gowirelessnzltd/p-41.html

From your description, modem sounds like it has standard SMA connection, otherwise would need further info if you needed an adaptor.

Thanks very much for the info & recommendations.

Do you think a pair of these would still give a decent improvement? It looks like the gain in the 3000MHz range is around 9dBi looking at the specs, which is fairly similar.

Is mounting the two antenna at opposing 45deg angles like the below image still the best?

Yes they will do the job OK too. 5G is at a higher frequency, so the more gain the better. But those white triangle ones will still do a better job than the current choice of no antenna. And yes, on opposing 45° angles.
