The metal shielding in the base and repeater MII stations provide additional isolation from each other and misc external sources of RF. As we have seen many use the mobile for repeater systems and in most cases it does work satisfactorily. But you will find some installations where there will be interference to the repeater systems which would not be there if you had a few more db isolation. The MII isolation curves are with a standard metal chassis and cabinet and not the mobile. You roll the dice and take your chances when you use any mobile/mobiles for repeater installations at shared sites.
