Think of "The Distance Away" from Sources of Noise as
being your Friend. [ Less Noise -and- Stronger Signals ]

# 1 - 10-25 Feet "Away From" The House / Structure.

# 2 - 10-25 Feet "Up Above" The Ground / Surface of the Stucture.

# 3 - Combining both #1 and #2 are even better.

As you move the Antenna Element 'away-from' things
that are the Sources of RFI /EMF the Signal Strength
of the Noise becomes Less by the Square of the Distance

Distance and Signal Strength
1-Foot-Away = 1 Unit of Signal Strength relative to 1-Foot-Away

2-Feet-Away = 1/4th Unit of Signal Strength relative to 1-Foot-Away

3-Feet-Away = 1/9th Unit of Signal Strength relative to 1-Foot-Away

4-Feet-Away = 1/16th Unit of Signal Strength relative to 1-Foot-Away

5-Feet-Away = 1/25th Unit of Signal Strength relative to 1-Foot-Away

10-Feet-Away = 1/100th Unit of Signal Strength relative to 1-Foot-Away

15-Feet-Away = 1/225th Unit of Signal Strength relative to 1-Foot-Away

20-Feet-Away = 1/400th Unit of Signal Strength relative to 1-Foot-Away

25-Feet-Away = 1/625th Unit of Signal Strength relative to 1-Foot-Away

Now if the Signal Strength of the Broadcast Signals at each
Distance were to remain the same : Then the Relative
Signal-to-Noise Ratio would run-out like this :

1-Foot-Away = Signal-to-Noise Ratio = 1:1

2-Foot-Away = Signal-to-Noise Ratio = 1:1/2 ~ 2:1

3-Foot-Away = Signal-to-Noise Ratio = 1:1/9 ~ 9:1

4-Foot-Away = Signal-to-Noise Ratio = 1:1/16 ~ 16:1

5-Foot-Away = Signal-to-Noise Ratio = 1:1/25 ~ 25:1

10-Foot-Away = Signal-to-Noise Ratio = 1:1/100 ~ 100:1

15-Foot-Away = Signal-to-Noise Ratio = 1:1/225 ~ 225:1

20-Foot-Away = Signal-to-Noise Ratio = 1:1/400 ~ 400:1

25-Foot-Away = Signal-to-Noise Ratio = 1:1/625 ~ 625:1

The Bottom Line : Distance 'away' from Sources of Noise
is your Friend.

BEYOND THIS IS - The Ever Expand Sources-of-Noise
[ Circles-of-Noise in a World Full of Noise ]

1 - Starting with the Primary Point-of-Noise
[ First Circle of Noise ] Remember -It All Begins With You.
= = = Your Very Own House (1X-to-the-X)

2 - Second Circle of Noise
= = = The Houses of your Next-Door-Neighbors (8 X/Distance Away)

3 - Third Circle of Noise
= = = The Houses of your Near-by-Neighbors (64 X/Distance Away)

4 - Fourth Circle of Noise
= = = The Houses within your Neighborhood (512 X/Distance Away)

5 - Fifth Circle of Noise
= = = The Houses and Buildings in your City (16K X/Distance Away)

6 - Sixth Circle of Noise
= = = The Everything in your State (4M X/Distance Away)

7 - Seventh Circle of Noise
= = = The Everything in your Nation (256M X/Distance Away)

8 - Eigth Circle of Noise
= = = The Everything in the World (66B X/Distance Away)

9 - Ninth Circle of Noise
= = = The Everything in the Solar System (4T X/Distance Away)

All That Noise - It's beginning to Boogle-the-Mind
-but- Our Friend "Distance" Helps Out ! )
