Six Meter Dipole

by on July 12, 2010

This is another video to help you get on six meter. In this video I explain the half wave dipole antenna and show as an example the dipole that I built. A half wave dipole is one of the simplest antennas that you can build. The dipole is usually two pieces of wire, attached to a center insulator. The dipole is fed with coax, with the center conductor going to one wire and the shield going to the other wire. The formula to calculate the length of the antenna is Length in feet = 468/ Freq in MHz. So for six meter with 50.125 as the target frequency this works out to 9.34 feet or 4.67 for each of the two wires. Here is a link to a dipole calculator www.kwarc.org I build my dipole using ½ aluminum tubing attached to a center insulator that I build out of a piece of Plexiglas scrap that I picked up for free from a window glass store. I added various nuts, bolts, and u-bolts to make up the center insulator. You could also make the dipole by inserting some number 12 or 14 wire inside ½ inch pvc tubing. Or, hang the wire dipole from a tree. When you build the dipole cut your tubing or wire long, then trim to length by using an SWR meter or antenna analyzer. I use my MFJ antenna analyzer to help me tune my dipole. I also show my Elk Antennas dual band beam that mounts on the top of the mast. You can learn more about Elk at www.elkantennas.com I hope this is enough information to help you put together a simple antenna to give six meters a try. Randy

A short video of me (KA6TRF) during the ARRL 2009 10 Meter Contest using a HTX-100 at 25 watts into a Dipole in Colorado Springs. I got 29 contacts with a number of them from other states including GA, LA, MI, MS, WA, TX, CO, AL, and Brazil. Durng this video you can hear a number of stations I made contact with during the 2009 ARRL 10 Meter Contest, including ZX5J operated by some young ham operators. On Sunday afternoon I was given a 5-9 and contact # 964 by ZX5J. I read that PP5JR was supporting the young contest operators at ZX5J, and you can hear him in the background. www.ka6trf.com
