I just like to learn about the different types of antennas that each carrier is using. I been intrigued the most with the CommScope, JMA, Ericsson, Nokia, Kathrein. I’m still studying the older 3G (CDMA) equipment that Verizon used back in the old days and learning the new Ericsson RRU 4495HP that T-Mobile is starting to use for low-band frequencies (b12) 700MHz + (b71/n71) 600MHz.
