Planning the System
Start by defining the coverage area you need, the users who will rely on the repeater and any existing structures you can use for mounting.
Core Hardware Components
A basic system includes a repeater cabinet, duplexer, feed line and an antenna mounted as high and clear as practical.
Licensing and Coordination
In many regions you will need a license and possibly frequency coordination to operate a fixed repeater legally and without causing interference.
Installation and Testing
Once everything is wired and powered, walk test the property with handhelds, checking audio in weak spots and fine tuning antenna placement.
