 Voltage baluns are easier to make and will work in any number of situations.  Current baluns, while more difficult, tend to be more effective over a greater range of circumstances, balancing the current on both sides of the antenna.  Usually, any balun is better than no balun. K8KIZ 7/2014

With neater turns, this free form ‘UGLY’ balun is as good as the one above! K8KIZ 7/2014 Photo Credit: K3DAV

 Both voltage and current baluns are available from a number of manufacturers.  Making your own is definitely within the capability of the average ham.  Using a readily available kit, you can save at least 60% off the price of a commercial unit. K8KIZ 7/2014
