Antenna Measurement Systems

Diamond Engineering Logo

Diamond Engineering was founded in 1989 in the Sierra Nevada foothills by Michael Hillbun as a microwave R&D lab providing RF system design, prototyping, and evaluation services. Since then, we have advanced to offer measurement and automation hardware, software, and design services for the RF and wireless industry.  We develop everything from standard measurement products to complete engineered solutions.  We routinely work with major corporations, universities and government agencies around the world to help them meet their RF and microwave testing needs.

Do you have special requirements or a custom project in mind?

Let us know and one of our engineers will work directly with you on a solution exclusive to your needs.

The new Diamond Engineering Full Spherical Mount is now a DAMS platform option that may be added to any DAMS platform.

The mount utilizes delrin for ball bearings and structure, plus it enables full spherical measurements to resolutions as low as 0.1 degrees.

The mount is ideal for unobstructed gain data and efficiency.

The belt driven system is a plug and play substitution to the DAMS elevation motor.

Features include:

Low reflection - 90% delrin construction

DC - 18 GHz or DC - 40 GHz

6-inch horizontal adjustment for centring

12-inch vertical height

0.1 degree movement resolution

5-pound load capacity (option 5)

10-pound load capacity (option 10)

CTIA and general efficiency software

Runs from existing platform elevation plug
