"Large" volume antenna
I have just made a larger than usual antenna that radiates well below
the broadcast band so I may study generated radiation patterns. The antenna is on a structure that rotates as well as a tipping action, all about 4 feet above the ground. Initially I will just listen to signal variences when aim and tilt is in the best position. I recognise that I may have to put a digital meter across the S meter terminals together with a holding capacitor but for the moment I will be guided by the S meter. On the upper frequencies I will hook up to a TV for a visual. SWR readings will be initially recorded across all frequencies in the horizontal position to be used as a datum which certainly be required as shielding is added in the near future. Comments? Regards Art |

snip more nonsense Comments? Not up to your usual standards, but it sounds like you made an antenna that is much much too small and won't see any directionality unluss it's operating (too put it simple for you) as a magnetic antenna. You'll notice if it works 90 degrees from what you'd expect. Regards Art No regard for you tom K0TAR |

How much will you pay for the movie rights? Art |
