Wideband antennae are suitable for SDR because they give you more bandwidth to play with. A broadband connection wouldn’t really help here because that’s really for telecommunications and nothing more. For SDR, you need to think more – or wide. And, that’s where a wideband antenna comes into the picture.
Top Recommendation for Ultra Wide Band Antennas
Since we live in an advanced era where everything needs to be wireless, wireless communication is on the rise. The demand is more than ever before along with the need for speed. Wideband antennae satisfy this along with a promise of low power consumption. They are also affordable.
However, we see that users are often confused when it comes to purchasing. Which one should they buy – there are so many varieties in the market! Well, the answer’s easy. We have done the research so that you don’t struggle with it. Below are our favorites (we are sure they will become your favorites too!)
1. TSA900 – Ultra-wideband Antenna
The TSA900 is a popular choice for SDR, Radar, EMC, and GPR. It has a wide range of attractive features that will compel you to buy it. Let’s see what these features are:
- It is a UWD or ultra-wideband antenna covering 900 MHz to 12 GHz.
- It is ideal for most radio communications.
- You can also use it for direction finding and spectrum analysis.
- It promises ADS-B reception at 978 and 1090 MHz.
- It is specifically designed for use with SDRs indoors. You may not get what’s advertised while using it outdoors.
2. High-Gain UWB Antenna
If you are looking for a high-gain directional antenna, you should definitely explore this one. Along with a very wide bandwidth, it offers multiple exciting features. A few are as follows:
- The bandwidth range is 700 MHz to 8 GHz.
- Its VSWR is usually less than 2.
- Its compact size makes it a better choice than its counterparts.
- The antenna has varied uses right from SDR to 5G, HDTV, UWB, Radar, IoT, Drone FPV, and GPS.
- You can also use it for direction finding, research projects, design projects, and electromagnetic surveillance.
3. RFSPACE – Ultra-wideband Antenna
The RFSPACE antenna has a wide range of applications and reach. It is also among the most reliable antennae in the market for the following reasons:
- It is a flat-gain antenna with VSWR and impulse response.
- You can use it for a variety of purposes including radio communications, LTE, IoT, GSM, PCS, WiFi, HDTV, spectrum analysis, EMC testing, and direction finding.
- With this antenna, you get ADS-B reception at 978 and 1080 MHz.
- It has a Vivaldi tapered slot.
4. AEcreative – Wideband Antenna Bundle
Instead of just the antenna, if you are looking for a bundle, you will like this one. It comes with everything you need to setup the antenna. Let’s take a closer look:
- It has a 10-inch cable that has been tuned to perform as expected and receive the signal well. The bundle also has a BNC or SMA adapter and a receiver scanner with a BNC or SMA base.
- The antenna fits all popular requirements such as RadioShack, Whistler, Uniden, mobile scanners, and other wideband reception.
- The receive frequency ranges from 50 to 1200 MHz.
- It can be mounted on glass. The package includes double sided tape for easy mounting.
5. RaTLSnake M6 v2 – 3-Antenna Bundle
This is a complete, low-cost bundle for SDR and many other SMA radios. It is extremely popular among users, which is why it has rightly earned the Amazon’s Choice tag. Let’s go through its features now:
- The bundle has a 2 meter cable that has been designed for low signal loss during transmission.
- There’s an antenna base and 3 masts for various applications such as for telescopes, DVB-T2, and helical.
- The antenna has an SMA male connector.
- It has been designed to reduce SWR mismatches.
- The base of the antenna is very sturdy, having been made of heavy-gauge metal. It improves shielding and ground plane coupling.
- The manufacturer offers a 1-year warranty.
Buying a wideband antenna for SDR can be a tedious experience because of the number of choices. It is also confusing if you are a beginner. We hope this guide has eased the confusion a fair bit, giving you an idea of what to choose.
