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
