How high should a 10 meter dipole be
http://www.dx-antennas.com/Height%20versus%20take%20off%20angle.htm WebIn practice, it might not be a problem but it you're expecting the max gain to be perpendicular to the elements, it's actually at more like 45 degrees. There will also be some nulls in the pattern around 20 degrees from perpendicular where you might think you'd hear somebody but can't. It's probably good enough to have fun with though. 1

WebAt .005 wavelength (1.35 ft high on 80M, or 0.66 ft on 40M ) field strength is down by 25dB. This is about 1/300 optimum transmit signal height signal level!!! We can reasonably expect, over very good soil, a 5-foot high 75 …
Web6 Meter Aluminum Dipole Antenna Parts list: The 6 meter dipole uses the same parts as the 10 meter model, less the 6-foot length of .5 inch tubing. Originally, plans specified a single set of ¾ inch saddle clamps and the much smaller element-to-boom plate DXE-BEB-3 - Polymer Plastic Boom to Element Bracket. rockay city ign reviewWebIn our example that would be a trim for about 14.287 MHz, or a dipole length of about 32.75 feet (32 feet, 9 inches). Cut the dipole wire to be a little longer than the computed length – it’s easier to cut wire than to extend it. rock baboon dndWebAdult Education. Basic Education. High School Diploma.
