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.
