8. on Isolation refers to the proper distance or separation needed to keep the Donor antenna signal pattern and the Coverage antenna signal pattern away from each other Isolation becomes particularly problematic when Omni directional antennas are used for both the Donor and the Coverage antennas Since these antennas transmit in a circle or more accurately a sphere it is very easy for these spheres to overlap and thus negate the repeater system 6 Production Operation 6 1 Notices Follow below safety items carefully before installation implementation maintenance and operation for this product BS and MS port must be connected to donor antenna and service antenna when powers supply on otherwise the equipment will be damage for long term use When use repeater for outdoor the distance between donor antenna and service antenna must be gt 20metes otherwise the repeater will be damage because isolation problem for long term use Donor antenna need to be lighting proof and lighting rod need to be install for donor antenna installation pole outside Check input power require input power less than maximum input power of repeater otherwise the repeater cannot work well Keep clear for label and indicator on surface of repeater to be identified 6 2 Installation Step 1 Start by taking phone up to the roof or other location outside to find where the signal is strongest Step 2 Temporarily mount the Donor ou
