Overhaul and Repair

Bring New Life to Your Aging System

Keeping an RF rotary joint operational at an affordable price is increasingly important in today’s environment. Scheduled maintenance can safeguard against catastrophic rotary joint failures; however, typical RF rotary joints are a forgotten maintenance item until the system fails. Once failure occurs, the original OEM may no longer support the older systems. That is why a qualified and reliable resource for proper maintenance is crucial.

Diamond Antenna and Microwave provides expert repair and maintenance of all RF rotary joints regardless of the original model or manufacturer.

In cases where Diamond Antenna was not the original supplier of the rotary coupler, it may become necessary to perform a limited amount of reverse engineering. Our technical experts oversee this activity, ensuring the part being analyzed is well understood and its repair or replacement is appropriate for the intended application. Wherever possible, the original supplier of critical individual components (e.g. seals, ball bearings, encoders, slip rings, etc.) is identified and contacted for assistance with the technical assessment of the item. Continued and involved discussions with our customers during the above process are routine.
