said by Spice300:The dish needs to be grounded to bleed off static charge accumulated by the transmitter radiating microwaves onto it to reduce the risk of a lightening strike.
Interesting. The "word" on the HughesNet community is that the purpose of the grounding is indeed to bleed off a static charge, but for the purposes of the static charge not interfering with the satellite signal. Apparently, it serves both purposes?
