WGBH-FM ROTOTILLER® FM Antenna on Great Blue Hill

 

The antenna pictured is an ERI Model SHPX-8AC built for WGBH-FM, Boston. The antenna is supported by an ERI LAMBDA™ Optimized FM Mounting System which ERI installed on the existing self-supporting WGBH-FM tower on Great Blue Hill. WGBH-FM is grandfathered and operates with an effective radiated power of 100 kW. ERI also installed the new antenna and the LAMBDA mounting structure.
