Description
Our Ringo Ranger II has more gain, less windload, and more mechanical integrity than other two meter antennas. You'll quickly appreciate the benefits of this amazing antenna! Based on the original W1BX Ringo, the Ringo Ranger II is the latest design featuring three 5/8 wave radiating elements and an adjustable 1/8 wave phasing stub.

:lol忠大 我才偷個懶 就麻煩你補齊了:lol

頻率範圍135~160幾乎涵蓋業餘VHF波段


重點是 . . . . . . 駐波可調整哦
