本文发表在 rolia.net 枫下论坛Grounding the satellite system to the central building ground helps
protect it and other components from lightning damage. Different
brands of satellite systems may have special grounding requirements.
However, dish installation should comply with local codes and the
National Electrical Code (NEC). Refer to your satellite system’s user
guides for any other additional grounding information. Grounding the
satellite system is something you can probably do yourself. But if
you’re not sure, you should contact a qualified electrician.

Acceptable central building ground points

• Grounded interior metal cold water pipe within five feet of the
point where it enters the building.
• Grounded metallic service raceway.
• Grounded electrical service equipment enclosure.
• Eight-foot grounding rod driven into the ground (only if bonded to
the central building ground by #6 or heavier bonding wire).
• Other acceptable grounding electrodes that comply with sections
250 and 810 of the National Electrical Code (NEC).更多精彩文章及讨论，请光临枫下论坛 rolia.net

  • 枫下家园 / 家用电器 / 室内天线如果加放大器是否可以收更多的台? -aix(AIX); 2008-2-4 {200} (#4237896@0)
    我有一个RadioShack 150-1857室内天线, 没有放大器, 只能收到以下频道:5,9,19, 25, 36, 41,47,52,57, 69.
    如果加一个放大器, 是否可以收到更多的频道? 请行家指教为谢!

      • Hi, is it safe without to connect ground, if there is a thunder, it will damage your TV,How do you connect the ground please -roolia(roolia); 2008-2-7 (#4245196@0)
        • 室内天线不需要接地。室外天线接地比较复杂，挖洞三公尺深，在洞内撒盐，盐上铺金属板，金属板上固定一个直径约一寸，长3.5米的铜棒，这个铜棒就是GROUND，接地不良对人和设备都有危害。。。 -noproblem(。o O); 2008-2-7 (#4245274@0)
