Available for Antennas 1.2m, 1.8m, 2.4m. The skyware global se –icing system is custom designed for our line of VSAT Tx/Tx antenna systems. A de-icing system prevents signal loss due to snow and ice build-up on the surface of the reflector. This system can easily be installed in the field using a socket wrench and cordless drill. Removal of two lower reflector bolts is necessary to install the defrost panel.
