How ever the varience is ever decreasing so I would say in the Ghz range it should be linear at something less than 2:1 So a normal transmitter will not require an external tuner as frequencies are *scanned. Real neat. Weight is in the order of 6.5 lbs and a weather balloon is capable of lifting 7 lbs so that is something to contemplate this summer for top band. Have the tilt set for approx 6 degrees which puts me above ground clutter and will leave it there to get some experience on different bands and conditions. Art So why haven't you already used it on 160, 80/75, 60, 40, 20, 17, 15, 12, 10, 6, or 2 and told use about your results? I am quite anxious to hear how well this works, because if it works well, I will be one of the first to make one. Please include signal reports from the station you work as well as signal reports concerning other stations they work. A very good frequency to try this on would be 14.300, as they are quite good net control operators. *If you work one of the 14.300 net controls, please include their callsign and the time you worked them. tom K0TAR Tom, he is never going to try the antenna or admit it doest work. Heck I built the stupid thing knowing it was a dummy load and a CBer's joke just to say I built it. (I was also very sick and bored at the time). It doesnt work because the impedance of the antenna consist primarily of ohmic resistance and dielectric losses. I doubt if he has ever buit the damned thing . Giving that the design of his antenna is a known CBers prank, I suspect Art comes from the same place. Unfortunately I also have known of someone else who behaves like Art. He was truly a brillant person who repaired banks tabulating machines back when they were all mechanical. He was brillant in more ways than just mechanics, a true rennisance man if ever I met one. Then he had a stroke. He latched on to this EXACT same "antenna" saying that he had designed it even though I knew of its CB use years before he discovered it. He used to be a good family friend until I showed him his antenna did not work comparing it side by side to a simple dipole. For Arts sake I hope he truly is just a prankster. I wouldnt wish the changes I saw on the poor guy I knew on anyone. I know I have seen the "antenna" before I knew it as a CB joke. I am pretty sure it was in my grandfathers collection of radio books which dated from the 20s to the 40s used as a dummy load. Jimmie |
