Ground Wire Question :
[Was : ground wire question]

TD Ton...

IMHO - On a scale of One-to-Ten (110) the direction
that a Ground Wire runs (routed) is about a Seven (7).

# 1 - Solid Connection to a Good Earthen Ground Rod / Point
# 2 - Bonding to the House's Electrical System
# 3 - Shortest possible distant / Shortest possible Ground Wire.
# 4 - Thick-Heavy-Large Size Ground Wire - The Ground Wire
should be at least 3X to 4X the Size of your Antenna Wire.
+ Add your own #s 5-10
So... What's On Your List When Designing and
Installing Your Radio Shack's Ground System ?

- I ground my masts and bond the co-ax shields to the masts.

1 - Grounded Masts - Good Idea.
Ground Rod placed right at the base of the Mast
and very short and heavy Ground Wire attached
right at the base of the Mast.
* Creates a primary {potential} Lightning Strike Point that
is well grounded and away from the House / Building.
- - - "The Remote Ground" -and- First-Strike-Point

2 - Bonding the Outer-Shield of the Coax Cable to the Mast
creates 'unity' between the two and provides a Path-to-Ground
via the Coax Cable to the Mast and "The Remote Ground"
-and- the First-Strike-Point

NOTE - Burying the Coax Cable between the Mast and the
House is also a Good Idea. Short Four Foot (4') "L" Shaped
'Ground Tubes' at the Mast and the House can also help.
WHAT-IS-AN - "L" Shaped 'Ground Tube'
Four Foot piece of 1/2" Copper Pipe bent into an "L" Shape
* Gental bend with a 6" Radius
* Short-Side-of-the-L = 12"-16"
* Long-Side-of-the-L = 32"-36"
* Run the Coax Cable through the Copper Pipes.
* Bury the Long-Side laying flat in the ground with
the Short-Side-End about 2"-4" above ground level.
* Bond {Connect} the Ground Tubes to the respective
Grounds at the Mast and the House.

- I use the IEC grounds at the indoor end.

David -Question- What is/are the "IEC" Grounds ?
- - - I.E.C = ? ? ?

- We don't have lightning here, but if it were to threaten
- I'd just unplug everything and throw the wires outside..

That works - But walking the Coax Cable back out to
the Mast is usually consider to be the better option.
Note-to-Self - This is tough to do if the Coax Cable is Buried ;-)

having fun cause the topic is radios and antennas - iane ~ RHF

IEC = 3 conductor detachable power cable

The cables are on the roof and come in through the windows. My house
is not air tight. We don't have extreme weather here, except when the
hills catch fire or turn to mudslides.

I bond shields to the masts because the masts are the shortest path to
ground. This is for friction static caused by the wind. The IECs
theoretically complete a ground loop, but that hasn't manifested
itself as an issue.

My house is stucco on metal lath and nothing penetrates the walls
except the neighbors' light dimmers, which come in on the mains.

David - Thank You ~ RHF

When we had one of the older homes (cicra 1911) in Oakland, CA
rewired for 220 VAC from 110 VAC. The Electrician who roughed
the new Main Circuit Breaker Service Panel was connected to the
same old Cold Water Pipe in the Ground as the old 110 VAC system.
My Daddy then had me install an 8-Ft Ground Rod within 4" of that
old Cold Water Pipe and Ground Connection and we then Bonded
the Ground Rod to the Cold Water Pipe and Main Service Panel.
- - - As My Daddy would say : "Now Son - It Is Done Right !"
-and- by inference : "Son You Know How To Do It Right [.]"
