| The
sunset of analog TV is fast approaching and at the time of writing this
paper is set for February 17, 2009. Existing broadcast towers have already
been analyzed and upgraded to support both analog and digital antennas and
transmission lines. But what happens when there is no longer analog
broadcasting? What happens to the structural integrity of the tower if the
analog equipment is removed? What happens if the digital equipment is
relocated on the tower? This paper will present multiple antenna
configurations on guyed towers converting from analog/digital broadcasting
to digital only broadcasting. The effects this conversion has on towers
are investigated and solutions presented. This paper will also show how
less equipment on guyed broadcast towers can result in higher loads in the
structural members of the tower. |
