Frequently Asked Questions

Q: What devices is this 433MHz dipole antenna compatible with?

A: This 433MHz half-wave dipole antenna is compatible with any device that operates at the 433MHz frequency range and uses an SMA female port, including LoRa gateways, remote control modules, wireless sensors, IoT transceivers, and RF communication systems.

Q: How does the magnetic base work for mounting?

A: The integrated magnetic base attaches instantly and securely to any ferrous (iron or steel) surface, such as metal enclosures, vehicle rooftops, equipment panels, or server racks — no adhesives, screws, or drilling required. Simply place it and reposition as needed.

Q: What is the advantage of a half-wave dipole design over a standard antenna?

A: A pure copper half-wave dipole antenna is specifically tuned to the target frequency (433MHz) for optimal signal transmission and reception. Compared to basic stub antennas, the half-wave dipole construction delivers noticeably improved electromagnetic wave performance, resulting in a stronger, more reliable wireless connection at greater distances.

Q: What cable type is included, and does it affect signal quality?

A: The antenna uses an RG-174 coaxial cable, which offers a good balance of flexibility and low signal loss for short cable runs. This makes it ideal for compact installations where routing the cable through tight spaces is necessary while maintaining solid signal integrity.
