To whom it may concern: I am pleased to recommend Ankur Singhal for his work in the RF DAS engineering field. I had the pleasure of working with Ankur during his time as RF DAS Engineer for American Tower Corporation and his knowledge of the field was remarkable. I worked directly with him on numerous projects and fully understand his capabilities. Ankur demonstrated the ability to complete designs from start to finish and was able to explain every detail to the project team members. With his vast knowledge, every conversation with Ankur was a learning experience for everyone involved. He always took the time to make sure the team had answers to all questions and was always happy to provide these answers. His knowledge of DAS and the design process is unparalleled by any engineer I have met. Ankur displayed an outstanding ability to lead and work with others. He would lead pre-construction project walks and recommend solutions to physical limitations found on site. His attention to detail is unmatched and this showed in all of his designs. Ankur consistently produced constructible designs and was a large factor to the success of our projects. With his knowledge and ability, Ankur will become an asset to any company he joins. It is my pleasure to recommend him and if I can be of any further assistance, please feel free to contact me. Yours Sincerely, Kevin J. Chase
