Is coaxial cable an option for distances of around 150 m to transfer SDI digital signals
300 Feet is about as far as you can take SDI or HD-SDI; before it needs to be reclocked. So no, 150 M is too far. Also the quality of cable; and if it's being run in parallel with other cables that cause interference can affect how long you can go. 

You can reclock at the half way point using a distribution amplifier, and you'll lose 1 frame of sync for each time you reclock. 

Your next best option is to run Fiber Optic; which you can run for 25 miles without having to deal with any signal loss issues.
