For One and All,
Better Signal-to-Noise Ratio from a Combination of Improvements
including . . . a Ground.
http://groups.yahoo.com/group/Shortw...a/message/5961
What I generally 'see' as far as an "Improvement" of the
quality of the RF Signal getting to the Receiver is from a combination
of things.
1. The Wire Antenna Element is placed farther from the House.
2. A 'remote' Ground Rod is used : Again this Ground Rod
is planted in the ground farther away from the House.
3. Use of a Matching Transformer between the Wire Antenna
Element and the Coax Cable : Mounted the Matching Transformer
on the Ground Rod - if possible.
4. Use of a Coax Cable Feed-in-Line : Laying-On -or-
Buried-Under the Ground - if possible.
5. The Extra Mile - Use a well grounded Lightning Arrestor
and/or an In-Line 1:1 Isolation Transformer where the Coax
Cable leaves the Ground and enters the House.
NOTE - All the above is no good if you do not have a very well
Grounded Household Electrical System. Do This First !
RESULTS - Actually in most instances what I 'see' is a reduction
in the S-Meter reading : But I also "Hear" a Greater Reduction
of the Noise Level. Thus the Signal-to-Noise Radio 'improves'
and the Listenability of the RF Signal (Audio) is much Better.
BUT REMEMBER - YOUR PRIMARY USE OF A GROUND IS FOR IMPROVED ELECTRICAL
SAFETY AND LIGHTNING PROTECTION - USE IT [.]

Neither do I. My experience is the same.
I have never witnessed a signal improvement from the use
of a variety of different RF grounds. It think it's
possible that once or twice I think I heard a small
reduction in noise.
I suspect that my house electrical system provides
sufficient ground to yield the maximum differential
between what's on my antenna and ground.
