Antennas improperly installed or installed to an inadequate structure are very susceptible to 

wind damage. This damage can be very serious or even life threatening. The owner and installer 

assumes full responsibility that the installation is structurally sound to support all loads (weight, 

wind & ice) and properly sealed against leaks. The manufacturer will not accept liability for any 

damage caused by a satellite system due to the many unknown variable applications.

even cut off the signal completely.
