Hello all,

Thinking about buying the below antenna, appears to have good reviews, decent modern look, easy to install. Would you guys recommend grounding it? Or does it not require it? Or does it depend?

DINOVA BOSS MIX antenna

Thanks in advance!

The antenna itself, no. The structure the antenna is attached to, depends, but probably not.

NEC 810.15 dictates that the mast be grounded.
NEC 810.20(A) dictates that an "antenna discharge unit" (grounding block) be used on the cable.

NEC defines grounding as running wires of a specific minimum size to a "bonded ground" that attaches to your service entrance ground. This may involve multiple ground rods and connecting wires between them.

Similar to this thread, I've gotten conflicting opinions on whether I should/am required to ground the structure the antenna is connected to. Does the structure I attach the antenna to make a difference? (i.e. a mast vs attaching it to something else)

Antenna grounding only involves the mast and the downlead.

It's not required, but it can prevent lightning strikes and surges.

Nothing will prevent lightning strikes. The best you can hope for is to route as much of the energy as possible away from your living space.

Grounding is designed to reduce the potential difference in charge between your antenna and the clouds so the lightening strikes somewhere else. It IS going to strike, just don't encourage it.

Grounding doesn't make your antenna invisible to lightning.

ALL antennas must be grounded to NEC code whether mounted outdoors or in the attic.

That way it helps fry everything in the house at the same time. MUCH more efficient that way!

So i take it you too have a problem with the current NEC code?

I’m not qualified to have a problem.

My training was in the Navy, and courses I took since. My last formal class was run by a Master who was retiring. Let us say, he kinda had nothing to lose and taught us more than short runs.
