Description:
AW07A Antenna Analyzer is a small battery powered RF impedance analyzer. It can test the SWR status of the antenna, measure impedance and reactance components, and help you solve antenna problems. The unit consists of six basic components: a variable oscillator, a frequency counter, an independent oscillator, a 50 ohm RF bridge detector, an A/D converter, and a microcontroller. This compact product is designed to meet the needs of rugged construction and field testing. The operating frequency range of the device starts at HF and can reach up to 490 MHz. The operating frequency range of the device extends from 1.5 MHz to 71 MHz in six overlapping frequency bands, including SWR measurements at 110-185 MHz and 300-490 MHz

Q: Why sometimes your partner's voice is intermittent?
A: Please note that you are within normal communication range, If you want use radio in distance range, please change other antenna with a bigger output power.If still same problem, please send the radio back to your authorized dealer repair.
Q: Can't turn on talky and even it is switch on, it often shuts off automatically?
A: Please check the battery contacts on the walkie talkie. If it is broken or twisted, please return the radio to your authorized dealer for maintenance during warranty.
Q: Can't transmit or receiver signal with other members?
A: First, please verify that the channel frequency and the CTCSS, you are used the same as those of your group members. Please make sure that you and your partners are all within the radio coverage, If the channel frequency and the CTCSS are the same.
Q: Why sometimes received voice from other groups?
A: Two way solutions.You can change another channel or change another channel frequency by PC software.
Q: Which is better -VHF or UHF?
A: epends on the terrain. The UHF signal is attenuated or absorbed by foliage, rough terrain and trees, VHF does better outdoors. The VHF has difficulties penetrating steel and concrete, UHF does better in and around buildings. If you use the radios in both environments, we prefer using UHF band.
