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 [.] i hope we are communicating - iane ~ RHF . . .. . = = = In , = = = "David G******" davidg******@c... wrote: JHR Wrote: "......

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. ~ Dave . - - - - - - - - - - - - - - - - - - - - - - - - - - - - .
