The TV satellite antennas are becoming bigger and heavier due to more HD channels being offered. 

I am now building these additional arms to use in conjunction with the UEM(Under Eve Mount) I already manufacture.

 This the simplest way to add strength and rigidity to combat the heavier, bigger satellite dish antennas. 

The whole concept of drilling holes into your roof or attaching a satellite dish antenna to your ceramic tile, that can vibrate in the wind, seems ridiculous. 

 The additional support arms are mounted from the bottom of the UEM to the two 24 inch on-center rafter tails on each side of the UEM.
