часто задаються

Q: Can you make a gooseneck antenna covering the full 320–350 MHz bandwidth?
A: We can customize a gooseneck antenna in this frequency range, but due to the relatively low operating frequency, the recommended effective bandwidth is about 14 МГц.
For best performance and stable VSWR, we suggest the working range be designed as 328–342 MHz instead of the full 320–350 MHz span.

If you need a specific center frequency, gain requirement, тип роз'єму, or length of the gooseneck section, we can further optimize the design. Feel free to share your detailed requirements.

Q: Why are there different antenna lengths and gains?
A: Due to different frequency requirements and performance needs, antenna length and gain will vary. Higher gain antennas are generally longer and provide better signal coverage.

Q: What antenna options are available for the 902–928 MHz frequency band?
A: For 902–928 MHz, we offer the following options:

• 30 cm length with 3 посилення дБі

• 50 cm length with 4 посилення дБі (+USD3)

• 65 cm length with 5 посилення дБі (+USD6)

Q: How do I choose the right antenna?
A: The selection depends on your application and required signal range. Shorter antennas are more compact, while longer antennas provide higher gain and better coverage.
