Upstream
      Freq/Power:    30.800 MHz     50 dBmV

Ese valor est� un poco bajo aunque dentro del rango que permite VTR 
(m�nimo 51, m�ximo 33)


Signal to Noise Ratio:      33 dB

Este tambi�n est� en el l�mite ya que es el m�nimo permitido.

Sin conocer el detalle de la instalaci�n se pueden mejorar siempre y 
cuando no hayan ductos o, por �ltimo, poner un amplificador.
