The most popular form of communication for sending and receiving moving pictures, generally with sound, is
television (TV). These transmissions are sent by either cable TV or DTH (Direct-To-Home). DTH is better than
cable TV because it provides higher-quality images and can reach rural locations that cable TV and terrestrial
transmission have not been able to reach. A crucial component of the DTH installation, the bracket must support
the weight of the antenna, feed horn (LNB converter), and wind force acting on the antenna surface. It is crucial
to signal reception since the quantity of signal received relies on the antenna's alignment angle. This interruption
in signal reception is often brought on by a malfunctioning bracket assembly used to install the dish antenna.
Therefore, it must have a strong enough bracket. The current research aims to investigate bracket failure and
plastic component failure mode effect analysis, or FMEA. To overcome the current chronic field failure,
optimization is done at the failure point site. Several design ideas were created, and the most practical idea was
chosen. FEA software programs were used to study the stresses on the bracket.
