Hello all,
Wondering if one of the techxperts folk on the group could please give me an explanation (in layman's terms) of what grounding actually IS and what is its importance to ensuring good reception for a Hamster such as myself. There are numerous resources on the net that do go some way TO providing an explanation, but I must admit most of it goes straight over my head as I don't HAVE that much experience in the subject. Over the past couple of weeks my radio has gradually been getting poorer reception and I am wondering if it is becuase of a problem with the unit itself, or because of some external factor. There has recently been some new building developments going up in my residential area so am wondering if this has HAD any influence? If it is due to 'grounding', what the heck can I do to resolve the issue? If it's of any help/consequence, my particular unit is the Buzz Aldrin G6 aviator radio (special limited edition). Thanks kindly in advance for any advice/resolutions. Kind Regards, Brian Anasta |

Kind Regards, Brian Anasta As far as antennas go, you want a good earth ground. Nothing beats an 8 ft. copper rod driven into good conducting ground. -- Regards, JS “The Constitution is not an instrument for the government to restrain the people, it’s an instrument for the people to restrain the government.” -- Patrick Henry |

There are much more complex aspects that you can explore when you feel the urge, just google about. -- Hello John & Bob, Thanks so much for the prompt replies. I've had a read through your comments as well as undertaken a bit more reading on the various ham websites, but there are a couple of things I can't get my head around. Firstly, John what do you mean by 'good conducting ground'? Does this refer to the geological aspects of the grounds, e.g. clay soil etc? My particular lot of land is heavy clay based and I'm wondering if this is having an effect.What do you recommend to be the ground which offers the best quality and can I improvise somehow to improve the ground where I live which as I mentioned is very heavy clay based. Secondly, Bob, when you talk about the 'counterpoise', is this the same as John refers to, i.e. the actual ground itself? Someone has recommended I should consider having someone put in a 220 line for an amplifier as he said that would make a perfect ham radio station. The person I spoke with, who in all honesty I don't think is an expert, also spoke about quarter wave verticals and RF energy. Now I think these concepts are above and beyond my skill-set but I am assuming RF refers to radio frequency? Thanks very much again guys for the help and explanations to an annoying newbie heh. Kind Regards, Brian Anasta |

Kind Regards, Brian Anasta Moist/wet earth is generally a better conductor of RF/electricity. Commercial broadcasters can spend much money on a "ground system" than the antenna, proper, and can actually end up being a sufficient counterpoise for the antenna, actually buried in the ground! In our world, it helps to have your ground stake(s) in a moist area of soil where the soil has good conductivity. Salts in the soil help with the soils conductivity. Since my ground state is at the corner of a well fertilized lawn this is achieved. With grounds, the bigger, more conductive, etc. is better. In the real world, we just settle for sufficient ...

Kind Regards, Brian Anasta Hi, Brian - I won't add to the good advice here on grounding, but reception / propagation has actually been worsening recently, owing to greater atmospheric noise and geomagnetic storms...plus the usual summertime blues. Don't worry, it'll pick up again. Bruce Jensen |

Just in regard to antennas though, I am becoming more aware of the importance of them to getting good reception. In regard to my little Grundig, would my antenna be of the SWL antenna variety? And what the heck sort of antennas are 'dipoles' and 'Yagi beams'?! I've never heard of those types before and wonder are these only found on the large-scale ham radio stations? Gotta love the names of them that's for sure hehe. Thanks so much for your help in advance. Kind Regards, Brian Anasta |
