The AJ977XF+ is a Fixed Reception Pattern Antenna (FRPA) designed to enhance GNSS resilience in interference-prone environments.
<ul class="wp-block-list"> <li>LEANA technology creates a 20 dB null over all azimuths, from ground level to an elevation angle of ~15°.</li> <li>XF+ technology provides additional protection by filtering out-of-band signals.</li> <li>The “+” technology supports two independent RF channels — if the L1 channel is jammed, the L2/L5 channel will continue to provide a usable signal (and vice versa).</li> </ul> <p><strong>Key takeaway:</strong> LEANA technology enables your GNSS receiver to function when it’s 10 times closer to a jammer or interference source compared to a standard antenna and receiver pair.</p> <p><strong><a href="https://www.calian.com/advanced-technologies/gnss/" target="_blank" rel="noopener">Click here</a></strong> to learn more about Calian GNSS. </p> <figure class="wp-block-image size-full"><img fetchpriority="high" decoding="async" width="800" height="800" src="http://coordinates.net/wp-content/uploads/2025/04/1742584217522.jpg" alt="Photo: Calian" class="wp-image-109586" srcset="http://coordinates.net/wp-content/uploads/2025/04/1742584217522.jpg 800w, https://www.gpsworld.com/wp-content/uploads/2025/03/1742584217522-300x300.jpg 300w, https://www.gpsworld.com/wp-content/uploads/2025/03/1742584217522-210x210.jpg 210w, https://www.gpsworld.com/wp-content/uploads/2025/03/1742584217522-768x768.jpg 768w" sizes="(max-width: 800px) 100vw, 800px" /><figcaption class="wp-element-caption">Photo: Calian </figcaption></figure> <p><p>The post <a rel="nofollow" href="https://www.gpsworld.com/aj977xf-gnss-anti-jam-and-interference-protection-with-low-elevation-angle-nulling-antenna/">AJ977XF+ | GNSS anti-jam and interference protection with low-elevation angle nulling antenna</a> first appeared on <a rel="nofollow" href="https://www.gpsworld.com">GPS World</a>.</p></p>
