Cyber Antennas visited Siglo in Mexico City to compare two asymmetrical 60° horn antennas (two HORN-A60s) with the RF Elements 5 GHz 60° 4x4 Asymmetrical Horn Antenna (AH60-4x4-SMA), using the same Cambium 4x4 ePMP 3000 access point. The ePMP 3000 radio had a 20 MHz channel at 5.45 GHz.
Cambium 4x4 ePMP 3000 horn test results: Cyber Antennas achieved twice the uplink RSSI on average across more than 60 CPEs.

Two Cyber Antennas HORN-A60 mounted side-by-side for 4x4 MU-MIMO operation with the Cambium ePMP 3000 5 GHz access point.
The RF Elements AH60-4x4-SMA horn antenna has both horns pointed in the same direction and wrap around the mast on three sides, requiring a standoff mount and preventing direct mounting to the tower.

The measurements for RF Elements were taken in the morning, while those for Cyber Antennas were taken in the afternoon, when environmental noise levels are typically higher. Despite this disadvantage, Cyber Antennas significantly outperformed RF Elements in the before-and-after comparison test, achieving an average 3 dB improvement. A 3 dB gain represents twice the signal power.
On the AH60-4x4-SMA product datasheet, RF Elements claims their 5 GHz 60° 4x4 Asymmetrical Horn Antenna has 16-17 dBi in 5 GHz from 5.1 to 6.0 GHz.
Cyber Antennas HORN-A60 only has 14-15 dBi of gain from 5.15-5.85 GHz, which is 1-2 dBi less gain than claimed by RF Elements on their AH60-4x4-SMA datasheet, except Cyber Antennas gain is realized gain as measured in an anechoic chamber.
While RF Elements lists “ideal” (theoretical) gain for an antenna feed that doesn’t actually exist, every other reputable antenna vendor reports measured (real-world) gain. This practice allows RF Elements to advertise inflated gain figures that are not achievable in practice, misleading customers into believing their antennas perform better than they actually do.
In addition of realizing double the signal power and SNRs, Cyber Antennas also support the entire 5 GHz and 6 GHz bands (from 4.9 to 7.125 GHz), which is particularly useful for international WISPs that can avoid Wi-Fi interference by operating outside the range of typical Wi-Fi routers (5.15-5.85 GHz).
In Mexico City, traditional frequency planning falls apart. Siglo is constantly scanning the spectrum for clean channels to operate in, and having the entire 5 GHz and 6 GHz band available is a basic requirement. RF Elements advertised frequency range for most of their 5 GHz horn antennas is 5180 - 6000 MHz, which does not even cover the entire 5 GHz band.
The 20° Cyber Antennas horns also help avoid noise thanks to their narrow beam widths, which pick up less interference from the intended coverage area—making them the top-performing sector horns in the WISP industry. It is the narrow beam widths of 20° and 30° horns that allow them to perform well in noisy environments, not “no side lobes.”
There has been a coordinated effort to protect industry favorite antenna vendors from fair criticism and competition; however, in the end, the best products will win. In 2025, this is becoming increasingly obvious.
Cyber Antennas takes WISP performance to the next level in terms of signal quality, speed, and—most importantly—reliability.
Siglo provides prepaid residential Wi-Fi internet services on a week-by-week basis. If there is any disruption in service, they immediately see the impact on their churn rate. Siglo also competes with every major Mexican national fiber to the home (FTTH) provider, including Telmex, Izzi, Totalplay, and Megacable. In such a highly competitive market, even small differences in subscriber churn rates will determine the viability and success of WISP businesses.
Siglo has grown to more than 10,000 subscribers since launching its WISP business in 2020, in one of the world’s most competitive and noise-polluted markets. Siglo has proven that, even in 2025, by providing high quality services, a residential PtMP WISP can remain competitive in one of the most cost-sensitive, interference-heavy metropolitan environments in the world. Cyber Antennas is proud to support Siglo by delivering the highest quality antennas, proving that high-quality wireless remains both viable and competitive.
