Typically for C-Bus underground cable use it needs to be a Cat5E UTP cable with the similar characteristics / impedance as the C-Bus 5005C305B cable.
If you use an underground CAT5E data cable from brands such as belden or garland etc
We would recommend you ask the supplier to provide confirmation they can provide a CAT5E UTP underground equivalent cable Gel filled.
Do not use shielded cabling.
