Grounding Using Cold Water Faucet
Count Floyd wrote:
I have heard a lot about grounding and using baluns, but I am using the cold water faucet in the back yard, it has an old-fashioned strap with a screw on the top that I put the ground wire in and tighten it down. Is this any good, or would something else be better? Thanks, Bob If the "cold water faucet in the backyard" is actually attached to the house, it will most likely not be directly grounded to the earth. Somewhere in the house there is a ground wire connecting the cold water plumbing to the electrical system ground, which is usually an outside ground rod. In that case the outside faucet is not a good RF ground. You would do better to build a ground system for your radio like the kind being discussed here in the other thread on this topic. |

SWL -Newbies- What About Grounding Your Radio Shack and Antennas?

It may appear to be iron pipe, but underground or in - your foundation or walls, it may convert to a run of PVC - or other material. Yes - That is true. - 2. If all iron pipe is present, washers, corroded fittings - or pipe sealing materials may make the ground a poor - one or create a ground loop with the electrical ground - of the receiver. Again - That is true. - 3. In many cases, the "ground" is actually via the mineral content of the water, not the pipe. In some areas, this is a lousy ground unless you are running salt water through the pipes. Actually the Ground 'connectivity' is the Mineralized Deposits encrusted within an 'old' cold Water Pipe that give it it's poor but uniform Conductivity along with the Water in the Pipe. -Thus- The Cold Water Pipe makes for a 'fair' Electrical Ground and RF Continuous Drain Grounding Point for the SWL's Radio Shack and Antennas. So getting to that Pipe at the point where it is just coming out of the Ground is the prefered -and- Getting down to the Main Water Feeder Pipe a few feet under-ground is better. - 4. As Telemon suggests, a system of radials is best - (that is why AM stations use them, too). For Transmitting Yes -but- Most Shortwave Radio Listeners (SWLs) do not need Radials to have an effective Receive "Only" Antenna. *The SWL simply needs a : * Good RF Signal Collector {Wire Antenna Element}. - = Radio / Receiver Connected between the two. = - * Fair RF Ground Return Path {Ground Rod}. - 5. It is a good idea to check if there is a ground loop - or difference of potential between your "real" ground - made of rods or radials and the electrical ground the - neutral on the power plug connects to. Technically and Legally they are required to be BONDED {Electrically and Mechanically Connected Together}. - A difference of potential can manifest itself in many ways, - including damaging the receiver, hum and noise, etc. Yes that is correct -including- Electical Shock, Fire, Loss of Home, Personal Injury and Loss of Life.
