📶 1 Piece 433Mhz SMA Plug Wireless Module Antenna with 5dbi Gain and 300cm RG174 Cable - Ideal for Walkie Talkies Review

As an IT specialist, I've seen some bad products, and this ranks up there with them! Thanks to my knowledge gained in practice, I tested and found that this "433Mhz Wireless Module Antenna Antenna" simply doesn't deliver what it promises. It's a cheap option, sure, but it just doesn't work with computers. In fact, it barely boosted the signal at all. Save yourself the money and invest in a more capable antenna.

I've had range problems on several iterations of antennas in a digital transmission project. This antenna was able to outperform all antennas I have tried. While it works on any surface, it seems to require the reflective nature of the metal base. The antenna itself has a magnetic base, so a steel car roof or steel roof canopy will greatly improve its performance.

To increase the range of the gate opener. Only minor improvements have been noticed with this external antenna, but most of this I believe is due to the very low power used by the transmitters I am using for this project.
