台美談判未涉匯率？外媒看市場波動揭「不能說的秘密」
新台幣連兩個交易日大升值，今（5）日盤中一度站上2字頭，由於時間點正好落在台美經貿談判結束之後，是否受到美方施壓升值新台幣，引起各界關注。行政院經貿辦與央行口徑一致，強調經貿談判沒有觸及匯率議題，重申美方沒有施壓。但外媒引述市場分析師看法指出，沒有經濟體會承認匯率是談判重點之一，以劇烈波動的反應來看，市場仍懷疑有美方介入。
儘管央行否認美國施壓新台幣升值，但英國《金融時報》報導，法國巴黎銀行（BNP Paribas）大中華區外匯及利率策略主管Ju Wang對此表示懷疑，她指出：「儘管沒有經濟體會正式承認貨幣估值是談判重點，但市場預期又是另一回事，尤其海湖莊園協議強調美元估值過高是美國貿易失衡的根本原因。」
針對新台幣狂漲，Ju Wang表示：「本地出口商恐慌，壽險業者避險不足，與股票相關的資金外流已經停止。」她表示：「央行仍是主要買家，但並未積極支撐市場，這引發外界懷疑貨幣估值是貿易談判的一部份。」

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.
