I'm Glenn - just signed up - looks like an interesting forum for sure. I'm retired from 36 years in telecom industry, Operations, Construction & Engineering - radio broadcast, two-way radio and the wireless (cellular) industry. Now that I have the time I'm building an antenna design business - particularly log-periodic type. My last 7 years was in management so I'm behind on my wireless field technology - however, looking forward to catching up. I'm just finished building a 'radio shack' for both commercial and amateur electronics bench work. I believe I can learn a lot from this forum. Thanks much!
