This JDTECK Dual Band Band Line Amplifier was designed specifically to provide a boost in signal downstream of a cellular repeater on a DAS in order to extend in-building coverage where signal may drop off due to long coaxial runs. It is designed to be installed after a repeater, not before as it has DL output but 0dB UL power. It also has gain in both directions. It features alarm monitoring LED’s to indicate error detection in the respective frequency band.
A test report is included with each line amp so you are assured of quality standards.

The level of Andy and Angel were amazing! They did our installation, and it was immaculate. They were professional, knowledgeable, and very meticulous. Best vendor I’ve ever worked with bar none! Professional customer service and technical knowledge was unmatched. JDTECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near future
From the beginning of the project JDTECK consistently impressed us with their knowledge and understanding of the technologies they produce and deploy. Their installations were consistently excellent and professional!
The level of professional customer service and technical knowledge was unmatched. JDTECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near fuI would like to take this opportunity to acknowledge JDTECK for exceeding our expectations in the design and installation of a DAS (Distributed Antenna System) for the MCU (Marine Corps University) Bldg. M285 located at Camp Johnson North Carolina
The level of professional customer service and technical knowledge was unmatched. Polk County Florida Roads and Drainage Division Complex is located in a very remote area with limited access to cell service in various areas. After installation of 5G cell service boosters, employees now enjoy an outstanding connection with their cell phones that was not possible before. Sales, design and installation were outstanding!TECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near future
In 2012 we found JDTECK and gave them a shot. Since then, we have never turned back. The equipment is quality, and meets all expectations, but most importantly the customer service, attention to detail and passion that goes into every single job, purchase etc is handled better than I could ever expect. I would highly recommend giving them a shot, and exploring their products, they will not disappoint
JDTECK did an amazing job with our 100,000 sq. ft. corporate HQ building. Large areas of the building experienced medium-to-poor reception, with frequent dropped calls and cell phone batteries constantly draining. When JDTECK finished, we showed full bars for all areas of the building. We actually get better signal strength inside the office than we do in the parking lot! Highly recommended!
The level of professional customer service and technical knowledge was unmatched. JDTECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near future
Your techs have been amazing! We wish all projects here were as seamless as this one. We tested the entire building, and it works well…
