An often visited conflict on a completed antenna and line project is the marking of the installed transmission lines. Make sure that you have the client provide you with a copy of their color code for their transmit and receive lines. Don't rely upon the, Do it like you normally do, statement from a project manager. There's a possibility he might not even know what the codes are and you can't afford a return trip. There is no industry standard and every carrier has their own marking requirements. Also, obtain a drawing of the hatch plate color code and installation details if the installation is within a monopole.
