Being Well Grounded is the Best Foundation for Every Radio Shack
 

Telamon - Well written except two little words were missing.

I know that but it still operates as a 'poor' to 'marginal' RF return.
The impedance is higher than what you would want for it to be a
good ground and worse it usually has plenty of noise on it so it
should be your last choice.

This is the very reason 'if' at all possible a separate Ground Wire
should be used as the "Primary" RF Ground to the Radios and
other equipment in the Radio Shack.

Especially if you are going to be using an External Antenna
which requires a Good Ground like an Inverted "L" Antenna
with a 9:1 Matching Transformer and Coax Cable feed-in-line.

Neutral?

There is a ground on the cable. Adding a second ground (or 3rd if
there is a 3 wire power cord) can cause more noise. In most urban
environments the RF improvement to be realized from having a fancy
receiver ground is buried way down in the noise floor. You'd be
better served by talking your neighbors into getting rid of their $5
light dimmers.

To Ground ? -or- Not To Ground ? {Your Radio} That is the Question !
 

For One and All,

To Ground ? -or- Not To Ground ? {Your Radio} That is the Question !
http://groups.yahoo.com/group/Shortw...a/message/9182

Is a 'separate' Ground Wire needed for a Radio
when it is already connected to the AC "Mains"
and a well grounded Antenna System ?

Is Grounding a Radio in the Shack a redundancy
when the Antenna System is well Grounded ?

Is the whole concept of a "Ground Window" for a
Radio Shack 'over kill' and a waste of money ?

2. Another situation is with old house wiring where there is no ground
in the AC mains system. Adding the ground would help with a single wire
Marconi type antenna.

1 and 2 above, the two exceptions, does not apply if a Hertzian antenna
is used.

A Marconi antenna is a 1/4 wave vertical radiator with a formal system
of ground radials. It is not just any old end fed monopole.

All you need is one good ground.Actually though,and I know I did once
post a guys webpage thingy in this here very,very newsgroup,,,, you just
might not need a ground at all.

I would ground for electrical safety first. Unless you're
transmitting that should be sufficient.

It's more than just an opinion. It is reasoning based on facts.

You are mixing up topics. Two threads got started on grounds at the same
time. We were posting about RF grounds and now you brought the "ground
window" into it. The "ground window" is for lightening protection not RF
ground.

Neutral?


The white in a normal 120V receptacle is an identified, grounded(1)
conductor. A white in a 120/240V outlet such as an electric dryer, is a
neutral. It carries any unbalanced load between the two hots.

All neutrals are identified, grounded conductors, but not all
identified, grounded conductors are neutrals.


(1) not to be confused with a groundING conductor.

According to the terminology in the CEC and NEC, the
"grounding" conductor is for the safety ground, i.e., the
green
or bare or green with a yellow stripe wire. The word
"neutral"
is reserved for the white when you have a circuit with more
than
one "hot" wire. Since the white wire is connected to neutral
and
the grounding conductor inside the panel, the proper term is
"grounded conductor". However, the potential confusion
between
"grounded conductor" and "grounding conductor" can lead to
potentially lethal mistakes - you should never use the bare
wire
as a "grounded conductor" or white wire as the "grounding
conductor",
even though they are connected together in the panel.

[But not in subpanels - subpanels are fed neutral and ground
separately from the main panel. Usually.]

Note: do not tape, colour or substitute other colour wires for
the
safety grounding conductor.

In the trade, and in common usage, the word "neutral" is used
for "grounded conductor". This FAQ uses "neutral" simply to
avoid potential confusion. We recommend that you use
"neutral"
too. Thus the white wire is always (except in some light
switch applications) neutral. Not ground.
