75 ohm Coax Cable for Vsat usage

Hi,
What is the important different between Outdoor and Indoor cable?
could I use the Cable for Outdoor that it said to proper in -40 to 80C( without explicit mention to Outdoor usage)?
Cable Datasheet give specification from Dc to 1.5Ghz. coul i use it throughout 0~2Ghz ?
Thanks for you help!

The main difference is the plastic outer insulation on outdoor cables is UV resistant, electrically they are identical.

Performance will fall as frequency increases, you can probably use the cable up to 2GHz with reduced performance but you would need a full specification from the manufacturer to confirm that. Often they designate a cable as being for a specific purpose and only show performance for that purpose when in reality it may be usable in other applications.
