It's like any antenna, only different. It is a lot bigger than most antennas. 418mhz =418 milliHertz= 0.418 Hz (MHz is MegaHertz) Wavelength is 718000 km ;-) Tom --- Email: ) Phone: +47 35972928/90662366, Ham call sign: LB8X Locator: JO49UA Snail: Tom Twist, Kirkeveien 8A, N3970 Langesund, Norway |

Doesn't sound very efficient. However any random chunk of a conductor will
