Charles, K5ZK, was wondering about the res. freq of his tower, 90' with KT34XA. After giving him a wise guy and SWAG reply, my curiosity was tickled, so I booted up EZNEC. Charles, I used a 90' tower, 12" in diam, with a 32'/3" boom at the top. ELNEC says resonant freq is 2.15 mhz. Bandwith is about 200 khz +/-. This might give you a starting point. FWIW, the 90' tower alone is resonant at about 2.6 mhz with abt 350 khz BW......... Again, good luck with the project. 73 K9WN Jake _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
