Portable U/V Pocket Yagi Antenna VHF 76-350Mhz UHF 250-500Mhz UHF Gain 8DBI VHF Gain 6DBI 25W. Thank you for choosing U/V Pocket Yagi. This antenna allows radio stations to increase communications distance, optimize signal quality, and improve anti-jamming capabilities. The unique gain directivity of its Yagi structure can also provide radio direction finding capability for radio stations.
It is suitable for radio communications, wildlife tracking and direction finding, and radio interference investigation. The antenna is designed as a foldable main beam, retractable vibrator, and is extremely portable. It is easy to store and expand quickly, and is a good assistant for outdoor radio work. Frequency range: VHF 76-350Mhz/ UHF 250-500Mhz - Antenna gains: UHF 8DBI; VHF 6DBI - Withstand power: 25W. 1 x Set of Yagi Antenna.The antenna has been equipped with UHF section vibrators. The vibrator unit near the grip is its reflection unit, the vibrator unit in the middle is the excitation unit, and the vibrator unit away from the grip is the guidance unit. Then adjust the length of the vibrator. UHF (430-440Mhz) tuning method: The lead unit does not pull out, the excitation unit pulls out the thinnest section, and the reflection unit pulls out the thinnest section and half. So far, the UHF band 430-440Mhz section has been tuned. UHF (409 public frequencies): The thinnest section of leading unit is pulled out. The two thinnest sections of excitation unit are pulled out. And the three thinnest sections of reflection unit are pulled out. VHF (144-148Mhz) tuning method: The excitation unit pulls out two and one third sections, and the reflection unit pulls out three sections. FM broadcast frequency (76-108, 98 MHz from center frequency): The excitation unit pulls out the finest 4 sections, and the reflection unit pulls out the thinnest 5 sections. The above are the adjustment parameters that cover common frequencies. If you need to use them on other frequency points, please cooperate with the equipment such as talent standing wave table to adjust them yourself.
When receiving a ground target, hold the grip, extend the arm flat, and vibrator unit perpendicular to the ground. If the oscillator is parallel to the ground, it will affect the gain lobe and make it form an angle with the ground, which is not conducive to long-distance ground communication. If you extend the feeder with an adapter, please adjust the length of the vibrator as appropriate.
It can carry out long-distance communication. The record of the longest connection of this antenna reaches 600km. Usually it cost about 35USD-50USD. If you receive defective item, please kindly notify us within 14 days.
