상품 특징

• 【Portable and Easy to Install】: The portable HF antenna backpack length is 13.58 inches. The total length after installation is 13.45 feet. This portable high frequency antenna can be easily installed by one person in 3 minutes. It is very suitable for outdoor or balcony installation.
• 【Supported Frequency】: This HF antenna can work in 8 bands: 131.23ft (40m), 98.42ft (30m), 65.61ft (20m), 55.77ft (17m), 49.21ft (15m), 39.37ft (12m), 32.8ft (10m) and 19.68ft (6m) (7MHz-50MHz). Impedance: 50Ω. SSB Max Power: 100W. The SWR of 131.23ft (40m) band is less than 1.3, while the SWR of other bands can be adjusted to 1.1, thus achieving a stable low SWR.
• 【High Reception Quality】: The PAC 12 HF vertical antenna is made of high-quality materials, and its 100W output power and 50 ohm impedance enable it to provide excellent signal gain and low noise performance, with a standing wave ratio (SWR) between 1.1 and 1.3, reducing power loss and improving antenna efficiency and signal quality.
• 【Reference operation】: [7MHz: Wrap 4 coils close to the side of the aluminum tube, retract the rod about 10cm, and the standing wave ratio is 1.1-1.3 (on the red line marked with silver). ] [14MHz: Wrap 6 coils close to the side of the telescopic antenna, retract the rod about 20cm, and the standing wave ratio is 1.1-1.3 (on the red line marked with gold). ] [21.4MHz: Use 4 sections of aluminum tubes plus 7 sections of telescopic antennas, pull out 10cm, standing wave ratio: 1.1-1.3. ] [29.6MHz: Use only the telescopic antenna, pull it out completely and then retract it about half a section, standing wave ratio: 1.2. ]
• 【Optimized and Upgraded】: Compared with the old model, this high-frequency antenna for amateur radio optimizes the load coil and adds shrapnel to the original load coil, which increases the strength of the shrapnel and makes the contact between it and the coil more reliable. It adopts slider adjustment, and you can switch the frequency band by simply sliding the slider with your finger.
