Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.
What causes the frequencies outside of the bandwidth to be unusable?
A: impedance match

Mimamsa gave rise to the study of philology and the philosophy of language. While their deep analysis of language and linguistics influenced other schools, their views were not shared by others. Mimamsakas considered the purpose and power of language was to clearly prescribe the proper, correct and right. In contrast, Vedantins extended the scope and value of language as a tool to also describe, develop and derive. Mimamsakas considered orderly, law-driven, procedural life as central purpose and noblest necessity of dharma and society, and divine (theistic) sustenance means to that end. The Mimamsa school was influential and foundational to the Vedanta school, with the difference that Mimamsa school developed and emphasized karmakanda (that part of the sruti which relates to ceremonial acts and sacrificial rites, the early parts of the Vedas), while the Vedanta school developed and emphasized jnanakanda (that portion of the Vedas which relates to knowledge of monism, the latter parts of the Vedas).
What did Mimamsakas and Vedantins agree on?
A: unanswerable

The first Digimon anime introduced the Digimon life cycle: They age in a similar fashion to real organisms, but do not die under normal circumstances because they are made of reconfigurable data, which can be seen throughout the show. Any Digimon that receives a fatal wound will dissolve into infinitesimal bits of data. The data then recomposes itself as a Digi-Egg, which will hatch when rubbed gently, and the Digimon goes through its life cycle again. Digimon who are reincarnated in this way will sometimes retain some or all their memories of their previous life. However, if a Digimon's data is completely destroyed, they will die.
What typically happens when digimon are killed?
A: Any Digimon that receives a fatal wound will dissolve into infinitesimal bits of data

Dumbwaiters are small freight elevators that are intended to carry food, books or other small freight loads rather than passengers. They often connect kitchens to rooms on other floors. they usually do not have the same safety features found in passenger elevators, like various ropes for redundancy. they have a lower capacity, and they can be up to 1 meter (3 ft.) tall. there's a control panel at every stop, that mimics the ones found in passenger elevators, like calling, door control, floor selection.
What is the height restriction on dumbwaiters?
A:
they can be up to 1 meter (3 ft.) tall
