| 21. | The first of them performed in Russian translation of Ivan Dmitrievsky had some elements of the antifeudal directivity.
|
| 22. | If the beam pattern and angle to the target are known, this directivity can be compensated for.
|
| 23. | The horn flare controls the coverage pattern, or directivity, and as an acoustic transformer, adds gain.
|
| 24. | A Yagi-Uda antenna's maximum directivity is 8.77 dBd = 10.92 dBi.
|
| 25. | In the nineties, Cabasse started to work on coaxial units in order to reduce directivity through spherical wavefront.
|
| 26. | For this reason, the resulting directivity of these devices is far higher than physically possible with any loudspeaker system.
|
| 27. | Materials that can attain negative permeability allow for properties such as small antenna size, high directivity and tunable frequency.
|
| 28. | The antenna only has a single radiation edge ( equivalent slot ) which lowers the directivity / gain of the antenna.
|
| 29. | Radio Moscow's shortwave ( SW ) transmission network has never been equalled in its transmission power, directivity and reach.
|
| 30. | Directivity is not directly measurable, and is calculated from the addition of the isolation and ( negative ) coupling measurements as:
