In the dark recesses of my memory, I remember seeing an article about determining trap L/C values by using an RF bridge to take measurements of the trap above and below the traps resonant refquency. Once the L/C values are determined, the resonant frequency can be calculated.
I also found this site with some more data: http://www.smeter.net/antennas/notatrap.php 73, Roger -- Remember the USS Liberty (AGTR-5) http://ussliberty.org/ _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
