 
 <prompt> A storage device wey dey use flash memory and no get any moving parts na wetin dem dey call solid state drive? Given di last question, write one context wey contain di answer. <response>: ```Instead, e dey often better make person get antenna wey e impedance no dey change too much over certain bandwidth. E come be say the amount of reactance wey dey show for the terminals of a resonant antenna when the frequency dey shift, like say, by 5%, dey depend well well on the diameter of the conductor wey dem use. A long thin wire wey dem use as half-wave dipole (or quarter wave monopole) go get reactance wey dey pass the resistive impedance wey e get for resonance, wey go cause poor match and generally unacceptable performance. If dem make the element using tube wey get diameter wey be like 1/50 of e length, e go result in reactance for this changed frequency wey no go too much, and e go cause less serious mismatch wey go only small-small spoil the antenna net performance. So, thick tubes dey typically use for the solid elements of antennas like Yagi-Uda arrays.```
