Direct burial coax cable

We are moving our internet services to a house which is serviceable yet there needs to be a line run from the home to the street, a total distance of about 700-feet. We planned on installing the line from the house ourselves, and are wondering if RG-11 Direct Burial Coax with a signal amplifier is the right type to use. The technician can then connect the buried line to the pole. We are wiring the connection into the house with RG-6 coax. Any feedback would be appreciated.
