Trying to rebuild several OLD KLM 144-148- 14 2M yagis (14el 17ft+ boom). Need to replace 4 DE insulators. These insulators were for 1.5" dia boom and 0.375 dia elements (split DEs). If anyone has some laying arou nd I could sure use 4ea. This model yagi used a 4el log-cell driven array. Arne N7KA N7KA at COMCAST dot NET
