Why should you connect your TV antenna to a metal rod that is driven into the ground?
Ikato28
The antenna becomes a lightning rod. By connecting the post it is attached to, to the ground via the metal rod driven into the ground, lightning will not pass along the antenna wire to your TV but will pass harmlessly through the post only.

∙ 15y agoIf you are mounting an antenna on top of your house or out on a pole, then you need to ground it from lightening strikes. IF you don't, the lighting will strike the tallest thing around your house and the current will flow through the wire and cause damage to anything and everything in your house. But I don't know how to do this. It usually involves attaching a wire and to a stake that is driven deep into the ground. You need to ask an expert. BTW, lightening struck a power pole next to my house and it traveled into my house. The lightening damage required me to replace a heater/air condition controls, dish washer, TV, and garage door opener. But it didn't harm my computer equipment.

∙ 11y agoMostly because an antenna is usually the tallest part of a house, and made of metal, which attracts lightning. if lightning hits the antenna it will follow use the metal rod to reach the ground instead of going through the house. Also partly because an antenna works better if it's grounded.

How do you ground a CB radio antenna?
Grounding is accomplished by connecting a heavy cable from the ground side of the antenna to a ground rod. A ground rod is typically a 4 - 8 foot copper plated steel rod driven into the ground as close as possible to the antenna, making the wire connection as short as possible. All equipment should also be grounded to a rod, not just the antenna.

How do you change the antenna on a 2005 Pontiac vibe?
If you do not have an antenna, u need to get something small like tweezers or needle nose pliers and pull the antenna ball ( from the mast) out to connect a universal antenna ( this can be tricky, you might have to stretch the mast opening). If you have an antenna you should only have to unscrew it and reattach a universal. I just completed this task on my 2004 vibe. Dealerships and auto shops were unable to assist me. Hope this helps! :)
