Wireless video systems all have one thing in common: antennas. Whether it’s a single one or an array of antennas, these devices are used to transmit and receive radio waves. So how do you choose the right antenna for your system to get the best out of it? Teradek tackles this question in one of their how-to articles, which is quite interesting to read, even if you are using other brands of wireless video systems. Well, I’ve personally become guilty of arranging the antennas of video transmitters with multiple antennas sitting on top of my camera in a way that probably compromised video transmission quality and range: I aligned some antennas at a 45º angle and left the rest straight. It felt… right. But it’s not, as Teradek explains in his How to Optimize Your Wireless Video System video. Check it out below! The accompanying blog post can be found on their website here. Although this is clearly a Teradek video featuring Teradek products, the underlying concepts apply to other makes and models as well, so I think it’s worth watching even if you use completely different wireless video systems. How to optimize wireless video First, it is important to understand and distinguish between the two basic types of antennas available to you: V antennas and H antennas. While V antennas (as in Vertical) use a vertical electric field, H antennas (as in Horizontal) use a horizontal electric field to distribute a wireless radio signal.
