I know this stuff is antenna-101, but I'm interested to see what the opinions here are Thanx in advance !!! Mike D. Northern NJ First, the balun shouldn't be up in the air. It should be close to the ground at the lower end of the vertical downlead wire of the inverted-L antenna. Then you can use a short, less than three feet, length of grounding wire from the balun to the rod. The ground wire should be at least 10-gauge, preferably larger, like 6 or 4-gauge. The coax should run on or in the ground to the house and then to the radio. This will prevent it from picking up noise on the coax shield, which can happen when the coax is up in the air. It's not absolutely necessary to ground the coax shield again near the radio if you follow the above advice. Thank you for all the replies. *My evil plan is this. *Since I cant get the matching transformer away from the house, I will secure it to the house's brick chimney. *The chimney goes all the way to the concrete foundation and should make an excellent ground.

Poor composition and petty personal attacks detract from what could have been a fine demonstration of the term non-sequitur. Our ratings board gives the posting a 3 1/2 out of ten. |

Since I cant get the matching transformer away from the house, I will secure it to the house's brick chimney. The chimney goes all the way to the concrete foundation and should make an excellent ground. Please explain why you think a 'brick chimney' will make an excellent ground. How about, the best thing approximating ground that is available on my roof ??? Michael Bricks are basically a ceramic material. Guess what the power companies use for insulators on their poles? That's right, ceramic insulators. One insulator a few inches tall can prevent thousands of volts from leaking to the ground from the wire. That should give you some idea of how far from electrical ground the top of the chimney really is. In fact the electrical resistance of a brick is so high it's almost impossible to measure it with normal test equipment. Here's an example: http://www.theanswerbank.co.uk/Scien...ion103133.html |

Poor composition and petty personal attacks detract from what could have been a fine demonstration of the term non-sequitur. Our ratings board gives the posting a 3 1/2 out of ten. I thought I made some good connections between what the OP thought was good idea, the earthen characteristics of RHF, and the utter uselessness of a concept fostered upon the clueless. Maybe you could provide a better example. What about the dead chicken ??? If I get a steroid free chicken from the Amish market, will it make a better ground then say a Tyson chicken ??? It does not matter what type of chicken you use. Open the bag and look at the dead chicken. That chicken has about as much a chance of being reanimated as your chimney has of being a good ground. Then give the dead chicken to MII for lunch. -- Telamon Ventura, California |
