copper plate antenna?
i just discovered a part of my roof which is flat, is covered with
copper, it measures about 50ft by 75ft and soldered it's still new so it shows good w/my ohmmeter just wondering as it's not grounded, if i tried to tune this up w/my tuner , how effective would this by on hf?? tnx |

You have this humongous plate to play with, but what is the other half of the antenna? 73's Richard Clark, KB7QHC |

Use some for of balanced line to the plate. Connect one side of the balanced line to the plate and leave the other empty. If you find another piece of metal there such as a gutter or vent pipe, you might consider connecting to it. While a balanced antenna might be best, you may find that just the copper plate works well. In the antenna handbook or ARRL handbook are end-fed antennas where the balanced line only feeds on one side to the antenna. This may not be the perfect antenna, but there is no reason it shouldn't at least work some. I have loaded up the screen door and talked across the country. It wasn't my ideal antenna, but it was fun to play with Good luck. Buck N4PGW -- 73 for now Buck N4PGW |

It will not work as a rediating antenna. I bet this setup could be
incorporated into an antenna system somehow though. We have some pretty sharp dudes in this group so if it's possibel that it will assist some type of antenna, this is the place to monitor.
