I am getting ready to mount a Yagi Y8066 800 MHz antenna on my roof. This is a receive only antenna used for scanning. The antenna mast itself is grounded properly to a ground rod via a #6 copper wire. I have no questions about this portion of the ground connection.
My question is; Is there any need to ground the coax itself (LMR-400) coming from the antenna to the scanner. I always have the option of disconnecting the coax during thunder storms and when not in use. However, I am a little nervous about having that coax running directly from the antenna into my home-office.
What do the rest of you guys do ? If there is a need for some type of grounding block in the coax path ? If so, can you provide a link to a recommended grounding block ?
Here is a diagram from the National Electric Code that shows a grounding block in the coax path. This is what is making me question if a grounding block is needed.

However, when I look for LMR-400 coax on the scanner master page I see multiple cables with an N-connector on one end and a BNC-male connector on the other end. This would lead me to believe that running a cable directly to the scanner is acceptable.
Thanks,
Dennis
