![]() "dansawyeror" wrote in message ... Tam, The description was for the coil. The total antenna is about 15 feet base to tip. The coil is about 1/3 of the way up. The base is about 3 feet off the ground so the tip would be about 18 feet up. Dan Tam/WB2TT wrote: "dansawyeror" wrote in message ... Frank, The coil measures about 60 uH. The antenna is elevated about 3 feet on a short tripod. The radials angle down the tripod legs and then out. The coil is about 4 inchs in diameter, number 12, wound on a fiberglass form. It is centerloaded. I am looking at it accross the yard, it is about 6 inches long. It is would with about a point .5 pitch. Calculations for a 1:1 pitch predict a Q of about 450. Thanks, Dan Maybe I missed something, but how high is the TOP of the antenna. I.E. How long is the whip? Is the loading coil at the base, or partway up the antenna? Tam/WB2TT Dan, Over perfect ground, I get an impedance of about 2.4 Ohms, with resonance very close to 3.8 MHz. What is the tallest tree in your yard? Tam |
