New LongWire Antenna - What Type Wire?
I like insulated multistrand bell wire. You can pay fro fancier wire, but
sooner or later, after a few years, the wire will get rusty and corroded and it will need to be replaced. Any hardware store or grange should have suitable wire. I'm not sure how long you want it to be, but make sure you have a static-lightening arrestor connected to it to protect your system s. All life all holiness come from you O Lord http://home.earthlink.net/~damienmj/index.htm http://home.earthlink.net/~damianomj/swallowindex.htm "James Douglas" wrote in message . .. As my existing fence is falling down and I have saved the 3K to replace it it's also time for a new antenna. What type of wire would be best? My existing antenna is around the fence about 8' in the area and the area is shaped like [ with the long side running North/South. |

I paid $25 at Lowe's Home Improvement for a 500' roll of 12g solid insulated -- course, that was a year or two ago. Might be $10-$15 higher now. The specialized wire places have nice wire -- and I've bought my share of it -- but basic copper is pretty cheap at the big-box stores. bob k5qwg |

All life all holiness come from you O Lord Thanks. I need all the holinesses I can gets. That's why I use the tinned stuff for contact antennas. For pole and insulator antennas I have this stuff from Home Depot called chandelier wire, whic is about 20 g twisted copper. It turns green but doesn't stretch or anything. That's what my 50 foot wire is. Between 2 egg insulators driving a Palomar MLB. I've also had excellent results with solid steel wire, which is $4 for 120 feet. |

My existing antenna is around the fence about 8' in the area and the area is shaped like [ with the long side running North/South. Considering 1. Price 2. Conductor performance. 3. Insulation longevity 1. Discount warehouse home improvement hardware stores. 2. If you were to hang it up on insulators where the wire would have to support its own weight I would give a different answer but you indicate that the new fence will support it so best and cheapest would be solid copper and large diameter. The RF current at medium wave and short wave has a tendency to travel on the exterior of the wire so the resistance to RF current flow is much higher than it is for DC, which tends to use more of the wires cross-sectional area. This Rf effect is know as the skin effect so since the RF current only travels in the "skin" of the wire a larger diameter for a long stretch provides a helpful improvement in performance. How big to go in diameter? Well bigger means larger circumference. According to this web page calculator 15 MHz has a rounded skin depth of 0.000662 inch. That's a pretty thin layer so a step in wire size must mean a significant drop in RF resistance per foot. I would go with the largest wire size available for a reasonable price. Something in the #6, 8 or 10 size would be a good bet. 3. Must withstand the sun and weather effects. Teflon coated is the same color of the fence would be a good choice. -- Telamon Ventura, California |

My existing antenna is around the fence about 8' in the area and the area is shaped like [ with the long side running North/South. I ended up getting 500' of #14 stranded copper, with 15mils insulation for $28.00, they wanted $32.00 for 200' taken from the large spool? WTF? Now I may extend the antenna to include a piece that runs across the top of the roof, which on my house is about 30' up in the air! Would that be good or bad, again I have 150' around the fence that runs in the shape of a C, what if I added a "extender" across the roof vent and ran a wire down the to main antenna? I have heard that "higher is better" I am also thinking about adding a two foot extension to the fence posts so that I can get the antenna up a little higher but am wondering what the neighbors are going to think? I do have a balun from Erickson Enginering, which seems to help so far although conditions have not been favorable here lately, and also have 8' copper rod pounded into the ground. |
