Residents came out to express their concerns to the Town Council about proposed cell phone antennae in two locations in Watertown. The concern is not just about possible health concerns from having a cell antenna near homes, but also about the new regulations that make it more difficult for communities to deny new cell phone antenna locations. Keenan Brinn, representing ExteNet — which is petitioning for the antennae — said the company seeks to put up one antenna on a utility pole at 141 Palfrey Street and one on a pole at 550 Arsenal Street. The company also seeks to put one near the main intersection of Watertown Square, in the vicinity of Charles River Road, but that falls under the Department of Conservation and Recreation’s jurisdiction. “ExteNet is interested in building out the fifth generation cellular network, otherwise know as 5G,” Brinn said.
