A movable coupler element varies the inductive coupling between the transmitter coil and the loops of the receiver coil as a function of the position of the coupler element.

The invention relates to an antenna coupler for testing a mobile radio device.

The upper coupler includes a handle moveable between up and down positions.

The invention relates to a mount (1) for a mobile radio terminal (0) and to an antenna coupler for a mobile radio terminal.

The coupler includes a rotary capacitive coupler.

The combined reactive coupler includes a magnetic coupler (12) and a capacitive coupler (13).

In one embodiment the radio is housed in a sealed meter, in another a coupler to a mobile phone is provided.

An integrated coupler may vertically integrate a hybrid coupler and a directional coupler.

Disclosed is an antenna coupler (1) for testing mobile radio devices.

A combiner selectively combines signals from the first receiver unit on a mobile terminal-by-mobile terminal basis.

The coupler may be secured to a movable tuning device by a plurality of securing members.

In certain examples, the seal can be provided upon movement of a moveable component of the coupler.

A coupler/coupling ring assembly comprises a coupler and a coupling ring that is removeably engageable with the coupler.

A coupler/coupling ring assembly comprises a coupler and a coupling ring that is removeably engageable with the coupler.
