Trouble-Shooting Guide ProblemSolutionWhat is standing wave ratio?
The standing wave ratio is a value indicating whether the antenna and the radio wave transmitting station match. If it is equal to 1, it means that the radio wave transmitted to the antenna does not have any reflection, and all are emitted, which is the most ideal situation. If the value is greater than 1, it means that a part of the electric wave is emitted back and eventually becomes heat, causing the feeder to heat up.Is the antenna standing wave guaranteed to be less than 1.5?The antenna is strictly tested by the comprehensive tester. The standing wave meets the technical parameters provided by the manufacturer (less than 1.5) in the applicable frequency range of the antenna, but the test result is affected by many factors such as frequency, antenna installation method, position, feeder, etc. Said standing wave can be used normally below 2.0What is the power rating of the antenna?
Antenna power resistance indicates the maximum power that the antenna can withstand, and is related to the antenna material and physical size, such as the coil diameter of the resonant coil and the thickness of the vibrator. When selecting an antenna, please ensure that the radio transmission power does not exceed the antenna's power consumption, so as to avoid antenna damage. The use of the hand platform in the car needs to be used with an external car antenna. There is no such thing as the power of the hand platform is small and the car antenna cannot be driven.How to choose long and short antennas?As far as the amateur antenna products on the market are concerned, the length of the antenna is usually proportional to the effect. The effect of the long antenna is better than that of the short antenna. Generally speaking, two antennas with a difference of 5-6 cm are not particularly obvious, but mainly The difference in the design of the structure, but the difference is 10-20 cm, the effect has a great relationship with the length. If you use the 144MHz band, it is recommended to select an antenna with a length of 70cm or more. The effect will be better.about the samples Policy
As each day we have so many samples to send, it won't be a small amount. So our company have the rules that the freight and sample cost should be paid by our customer.And once we receive your order, we'll return this money to you. I hope you could undertand us.What's your delivery time?
Within 12working days upon receive 100%TT deposit.How is your quality guaranteed??
A: Our quality warranty for one year, problem antennas could be replaced. But in generally speaking, our antenna quality is very good, there will be no problem, customers no need to worry.
