RFXTRX433xl - better antenna?

[DJF3]

Which (better) external antenna can I use for the RFXtrx433xl? I found older posts that all point to broken links or non EU(/NL) webshops.

I DO have an RFXLAN (yes, that must be >10 yrs old with an external antenna and (approx. 1-2m) coax cable but that connector is too big for the RFXtrx433.

- Is it easy to replace the connector with a new & smaller connector?
- (and) Where can I buy a better antenna

I have quite a number of sensors that work fine with the RFXLAN and it's external antenna but not with the RFXtrx433.

Cheers!
DJ
