ท่านมดดำ คุณสมบัติเสาต้นนี้มันเป็นยังไงครับ
แปลเอาเองนะครับ Outperforms 5/8 Wave AntennasAEA’s Hot Rod antennas are end-fed, half-wave dipoles which are shorter, lighter, and easier to use on handheld radios than 5/8 Wave antennas. They provide approximately 10 dB more gain than the popular “rubber duck?helical, quarter-wave antennas. The Hot Rods are also capable of managing over 25 watts of power, making them ideal portable base or mobile antennas. When collapsed, the Hot Rod antennas function electrically, like helical, quarter-wave, flexible antennas, and perform similarly to the “rubber duck?antennas. AEA offers two different commercial Hot Rod Models: HR-2 Hot Rod Half-Wave 220 MHz and the HR-3 Hot Rod Half-Wave 150 MHz.
Unique TechnologyWhy do other manufacturers market 5/8 wave instead of half-wave, handheld antennas? Because the matching network required for the mostly resistive 50 ohm feedpoint impedance of the 5/8 wave is much easier to manufacture than the matching network required for the 1000-1500 ohm feedpoint impedance of the half-wave antennas. AEA has solved this matching problem in the half-wave antenna, and at the same time has kept manufacturing costs low. This allows AEA to offer our customers high performance, affordable antennas for handheld units.
