Topband: Flooded CATV cables for TX

[Lennart M]

Like many of you I have been using "outdoor drop cable" for RX antennas without any problems.
Looking at the spec:s for the Italian brand CAVEL it says max current 8 A and Insulation voltage 8 kV. 8A but there is no stated power limit.
I believe the connectors are the weakest point when used for transmission.
Anyone using those cables for transmission and what are your experiences? 
Thanks in advance
