Glad you could confirm.<br />Finished your Tech Lessons today and did a practice test on eHam - passed. Think I'll go through your videos again before my real test on Jan 14. Can't thank you enough for all the effort you have put into helping us folks that are getting started in the field.Natehttps://www.blogger.com/profile/17332511736901459526noreply@blogger.comtag:blogger.com,1999:blog-5676523852041991979.post-48602237734369703522017-01-01T17:23:31.161-08:002017-01-01T17:23:31.161-08:00I'm on the road, but I will try to answer the ...I'm on the road, but I will try to answer the best with an iPhone in Vance County, NC. for the most part, the formula is a swag. It provides a fairly accurate length across all frequencies. The moral of the story is that a 1/4 wavelength vertical for 146 MHz is about 20" and will provide a relatively low SWR. Unfortunately, I was an archaeology major and daydreamed through math. Hope that helps. 73. -AndyAndyhttps://www.blogger.com/profile/07972687504772876019noreply@blogger.comtag:blogger.com,1999:blog-5676523852041991979.post-16732655812630528962017-01-01T13:28:20.899-08:002017-01-01T13:28:20.899-08:00Andy, I am loving your course. So Helpful.
Can yo...Andy, I am loving your course. So Helpful.<br />Can you tell me how this 1/4 or 1/2 length formula came to be the standard? it is a little "off". Using the 1/4 wave for 146 Mhz: The actual Wavelength of 146 Mhz based on the extact vaule of "c"/146 *10^6 = 2.0533 M <br />1/4 Wave = 0.5133 M = 20.208 inches.<br /><br />12 * (234 / 146) = 19.223 Inches.<br /><br />Am I missing something?
