Wi-fi video methods all have one factor in frequent: antennas. Whether or not it’s a single one or an array of antennas, these units are used to transmit and obtain radio waves. So how do you select the precise antenna to your system to get the perfect out of it? Teradek tackles this query in one in all their how-to articles, which is sort of fascinating to learn, even if you’re utilizing different manufacturers of wi-fi video methods.
Nicely, I’ve personally change into responsible of arranging the antennas of video transmitters with a number of antennas sitting on high of my digicam in a method that in all probability compromised video transmission high quality and vary: I aligned some antennas at a 45º angle and left the remaining straight.
It felt… proper. Nevertheless it’s not, as Teradek explains on this Learn how to Optimize Your Wi-fi Video System video. Test it out beneath! The accompanying weblog publish may be discovered on their web site right here.
Though that is clearly a Teradek video that includes Teradek merchandise, the underlying ideas apply to different makes and fashions as nicely, so I believe it’s value watching even should you use utterly completely different wi-fi video methods.

First, it is very important perceive and distinguish between the 2 primary forms of antennas out there to you: V antennas and H antennas. Whereas V antennas (as in Vertical) use a vertical electrical discipline, H antennas (as in Horizontal) use a horizontal electrical discipline to distribute a wi-fi radio sign.
Up to now, so easy, however how do you resolve which variant to decide on? Nicely, mainly you will have two modes at your disposal: V mode, which after all makes use of solely V antennas, or V+H mode, which makes use of H antennas on the outer ports, whereas V antennas fill the gaps in between.
V mode is nicely suited to long-range, direct line-of-sight connections, whereas V+H mode is best suited to a extra obstructed view that requires a extra sturdy sign that may minimize by way of interference and objects alongside the best way.
And, in reference to my preliminary assertion above, it’s best observe positioning the transmitter and receiver antennas perpendicular to the bottom, not at an angle like I did. That’s what the hinges on the antennas are literally for, so don’t attempt to create a elaborate however counterproductive sample right here. Simply level all of the antennas straight up and be accomplished with it.
Should you want a good stronger sign for very lengthy distances or sophisticated environments, Teradek has an answer with the Antenna Array for Bolt 4K, however that’s one other subject for one more day.
Utilizing essentially the most applicable antennas for the job and positioning them accurately will drastically have an effect on the standard of the transmission. Subsequently, comply with these pointers when utilizing a wi-fi video system within the discipline, whether or not it’s a Teradek product or another.
Since that is “primary” data for radio engineers, these ideas apply to virtually all makes and fashions. Positive, typically you’ll be able to’t even swap antennas as a result of they’re constructed into the gadget in query, however when you have a alternative, select correctly!
