Ordering: Due to lower than expected sales volumes we decided to cease production of the product rather than move the product out of country for manufacturing. AES is not willing to sacrifice product quality or robustness. We would like to thank all the wonderful folks that purchased our products and will continue to service those products moving forward.

All devices are designed with specifications for commercial environments and optimized for the amateur operator. Tested at extreme conditions and field proven, the AES, Inc. Passive Load Array (Dummy Load) and Digital Reflectometer (Watt Meter) are designed and specified for Continuous Commercial Service (CCS) performance - not ICAS (intermittent commercial and amateur service). That means you can run your station all night with no worry of failure. With Applied Engineering Science products, peak performance can be expected 24/7 – enabling the station operation to maximize performance and efficiency.

When you add AES, Inc. products to your station, you should expect user friendly interfaces and design. You won’t have to mess around with searching through menus or options. Everything you need is ready to go and simultaneously displays your operating conditions.

We mean what we say. Robust. Reliable. Rock Solid. Applied Engineering Science backs this up with a no nonsense one year warranty covering materials and workmanship.
