How to Choose an Antenna Analyzer
Even after learning about the best antenna analyzers on the market, choosing one can still be a bit challenging, especially if you don’t know what to look for. The following paragraphs shed light on the different factors that must be considered before purchasing an antenna analyzer.
When we speak of design, we’re mainly talking about whether the unit is shielded or unshielded. Shielded devices like the Hima Nanovna-F Vector Network Analyzer tend to flaunt metal casing that’s usually made of aluminum.
Shielded devices have two main advantages over their unshielded counterparts. Firstly, they’re way sturdier and offer better protection for their internal components. And secondly, these units are highly resistant to disturbances.
Shielded VNAs are excellent choices for beginners who don’t have much hands-on experience with antenna analyzers. However, if you’re an expert, you’ll probably need access to the VNA’s internal components for things such as changing the transceiver’s wiring. In this case, you’d be better off with an unshielded device since it’ll offer you easier access to internal components.
The frequency range is arguably the most important factor to consider when in the market for an antenna analyzer. The selection should be based mainly on the application with which you’ll use the VNA.
For example, if you need the device for a ham radio system, you need an analyzer with a range that covers the area just above the AM band all the way to the Citizens band. More specifically, you need a device that can cover the 16-27MHz range.
If you’re looking for an analyzer for weather tracking radio systems, you need a unit that’s able to cover higher frequencies.
We strongly recommend getting an antenna analyzer that features a broad frequency range so that you’re able to use it for a wide range of activities. Luckily, all of the devices reviewed in this article boast superb frequency ranges, so you won’t have a problem finding one that meets your needs.
Make sure to invest your money in a device that has a user-friendly interface and that’s easy to navigate. Most VNAs feature touchscreens of reasonable size that allow for easy navigation, so that shouldn’t be much of a problem.
There are also units like the RigExpert Zoom HF Analyzer that combine touchscreen navigation with physical buttons or switches for a more user-friendly experience.
When picking a VNA, you want to consider the size of the screen. Anything between 2-4 inches should be sufficient. Also, you want to consider the screen’s brightness. Of course, the brighter, the better, especially if you’re going to use your antenna analyzer outdoors.
The great thing about VNAs is that they’re very compact and lightweight, especially NanoVnas. However, there are units that are pretty bulky and heavy. Not to take anything away from these units, it’s just better to invest in an analyzer that’s small and light for easy handling.
Some units are more feature-packed than others, but that doesn’t necessarily make them better. The more features a device has, the steeper the learning curve will be, so make sure you invest your money in a device that offers just the features you need so you don’t get lost in the sauce.
It’s worth noting, however, that most of the devices on our list are backed by plenty of YouTube tutorials that help explain and demonstrate their features. So even if you were to go for a device that flaunts more features than you need, you’ll find it somewhat easy to get over their learning curve.
