Kobe生涯首冠戒售出 成交價3千萬破紀錄 | 蕃新聞

The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.

美國時間3月31日的交易截止日已過，確定布萊恩2000年首次獲得總冠軍的冠軍戒售出，價格高達92.7萬美元（逾3000萬新台幣），打破了歷史上NBA冠軍戒指的拍賣紀錄。
這枚冠軍戒由14K金打造，鑲有40枚鑽石，是布萊恩和歐尼爾2000年以4：2擊敗溜馬奪得的生涯首冠。戒指正面刻有湖人隊Logo和「世界冠軍」等字樣，兩側則分別刻有「Ring Bling」、總冠軍年份、布萊恩的名字以及當季湖人的戰績。底部則刻有布萊恩生涯初期的8號背號。
拍賣會在3月31日截止後，以92.7萬美元的價格成交，成為史上最高價售出的NBA冠軍戒指。之前的紀錄保持人是2021年拍賣的羅素1957年首次獲得的冠軍戒，當時售價為70.5萬美元（逾2200萬新台幣）。值得一提的是，此枚湖人冠軍戒並非正式贈送給球員的戒指。
原來，布萊恩在2000年獲得總冠軍後，自掏腰包向廠商額外訂製了一枚，送給了父親喬布萊恩。雖然不是唯一一枚，但仍具有極高的價值。如今，這枚冠軍戒在布萊恩逝世4年後被他的親生父親公開拍賣，引起了部分球迷的不滿和討論。
