Willtek Launches Antenna Coupler For TETRA Radio Testing
now test their radios without having to use type-specific RF (radio frequency) adapters. Willtek Communications recently introduced the first antenna coupler for TETRA frequencies, the Willtek 4914 Antenna Coupler. It complements the 2303 Stabilock, a dedicated TETRA mobile station tester for service in the field of PMR (professional mobile radio). The coupler can also be used for mobile phone systems operating in the 400 MHz range, such as CDMA-450.
The 4914 Antenna Coupler renders an individual RF adapter for each type of TETRA radio unnecessary. 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 becoming much easier. Without expensive and difficult to handle special adapters, it is 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.
Tom Riedl, Product Marketing Manager at Willtek Communications, said: "The new 4914 Antenna Coupler complements Willtek's TETRA product portfolio. Together with the 2303 Stabilock and the 4921 RF Shield, it constitutes a complete solution for ensuring that the radio equipment is fully functional. Proper communication tools are vital for the public safety and security services in a critical mission."
Willtek'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.
