Ismaning, Germany and Cheadle Hulme, UK — The first antenna coupler for TETRA frequencies from Willtek Communications, the Willtek 4914 renders an individual RF adapter for each type of TETRA radio unnecessary. Service and repair shops testing TETRA mobile phones can now test their radios without having to use type-specific RF (radio frequency) adapters.
The antenna coupler complements the 2303 Stabilock, a dedicated TETRA mobile station tester for service in the field of PMR (professional mobile radio). It can also be used for mobile phone systems operating in the 400 MHz range, such as CDMA-450.
The TETRA phone is placed on the shuttle of the 4914 which in turn is connected to the RF port of the radio test set. This way, handling is significantly simplified. Previously, without expensive and difficult to handle special adapters, it was almost impossible to test a hand-portable radio.
Radio shop managers can also raise the level of confidence in the TETRA equipment because the antenna is included in the test. Until now, the antenna was not used during the test but either dismounted or bypassed.
The company's 4914 antenna coupler enables users to reliably and safely test different hand-portable radios in a few steps. Handling has become so easy that the antenna coupler can even be used by untrained staff. The shuttle provided with the 4914 holds the radio terminal and allows for taking high precision measurements at good repeat accuracy because the radio is positioned accurately.
