WebHam Radio DipoleFormula. The formula to calculate the (approximate) overall physical length of a dipole is: Length (meters) = 142.58 / frequency (MHz) Length (feet) = 468 / frequency (MHz) The length of wire given by the formula is cut in half to make both sides of the dipole. The above formula gives an approximate result because the length at ... WebThe 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. The final arrangement is considerably stronger and

WebAn antenna like that, fed through a tuner with parallel feed line or coax with a decent balun at the feed point, would be MUCH more efficient than a 40 meter hamstick, by far. A hamstick on 40 meters, if you do everything right, is going to have an efficiency of around 10-15%. You put 100 watts into it, and it'll radiate about 10 to 15 watts. http://www.freqdev.com/ham/10%20Meter%20and%206%20Meter%20Rotatable%20Half%20Wave%20Dipole%20Antenna.pdf motor racing north east
