Dipole wire length calculator
WebHere is a list of favored Dipole lengths:* 40 to 41 meters - 132 to 135 ft. 34 to 35 meters - 111 to 115 ft. 26 to 27 meters - 85 to 88 ft. Feedline Lengths: The feedline length is also an important part of a "friendly" antenna design. When calculating optimum lengths, we must use the velocity factor of the feedline. http://www.csgnetwork.com/antennaevcalc.html

WebThe basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and inches or 143/freq-in-Mhz for meters . The inverted Vee antenna legs will be longer by 2 - 6% from those of the horizontal antenna depending on the angle. WebTo convert American Wire Gauge (AWG) to diameter: 1. Click Wire gauge to diameter. 2. Select the units of measurement, either English or Metric. 3. Type the gauge number in the Value box. (You can enter the largest gauges as 0 to 0000000, 1-0 to 7-0, or 1/0 to 7/0.) 4.

Hi Chris, Receiving antennas (especially for BC band) do not have to be 1/2λ, nor matched to coax cable. Try just a random length about 3m long, connected directly to the receiver terminal. If the receiver has a ground connection, try adding a short wire to a cold water pipe if it is metallic (PVC in my house), or to a driven ...
