Has anyone used a slinkey antenna? I bought one and hooked it to a tree in my yard about 30 ft up. I have a Grundig Yacht Boy 400 and I clipped it to the telescopic antenna. I dont see much improvement. Live in the Wa. state, is recption real bad here or should I update and get a newer radio? this one I bought new in 91.
Thanks, Clyde |

Thanks, Clyde Hi Clyde, That sounds like plenty of antenna for most SWLing - there's just not enough sunspots to hook it too. A new radio won't fix that. To those who are counting those sunspots (the missing ones), they have theories about that which also involve the freemasons, ancient astronauts, and other influences that will converge on a solution in 2012. The short explanation is that "time will tell." 73's Richard Clark, KB7QHC |

The antenna sold today as a "slinky" is not the slinky of old as shown in Jasik's book. If one is to put a lumped load into the schematics of an antenna then one MUST add a cancellation to the structure as the intent for maximum efficiency of radiation is the correct use of distributed loads only. The present day slinky consists of continuous length of wound inductance or a "lumped" load. The true slinky consists of equal amounts of clockwise and clockwise turns such that the lumped inductance is canceled leaving only distributed loads. O.T As far as the "soot" term being presently bandied around, it is an adjective which describes the chemical effects of combustion. Only those old in the tooth or unfamilier with physics describe it solely as a product of burning coaland nothing else! This is similar to the use of "waves" in physics with respect to particles. One is a noun, where the other is a adjective that describes the action of same. |

It's poor grade of Metal has a HIGH-RF Resistance. Unlike COPPER wire,
Those SLINKY Antennas, Get very WARM almost HOT, so you really know they do work, but very very inefficient. Like trying to Pump at 200 WATT STEREO into your electric shaver or light bulb!!!. If they were pure Copper, you'd have something to talk-About! Try making a QSO on a Bed Spring VERSUS a Dipole or Loop antenna. Same analogy........
