The EF's (Elite Force) haven't been listed for a while but when ever I hear of a commercial balun being used I remember how I got tired of them not standing up to 1500W and began making my own Ugly Baluns. No problems since then but if all else fails try it.... Russ K5ZZR http://www.force12inc.com/categories/elite-force.html My Heroes Wear Combat Boots!
