Thanks to its 200 MHz bandwidth, it reliably covers the entire operating range from <strong>2700 to 2900 MHz<\/strong>, making it convenient for use with the <a href=\"https:\/\/ft.systems\/en\/video-transmitter-vtx-ft-2-7\/\">FT VTX 2.7GHz<\/a> video transmitter.<\/p>\n<p data-path-to-node=\"2\">The <strong>21 dBi<\/strong> gain is the highest in the 2.8 GHz patch antenna lineup. The model forms a narrow beam pattern of <strong>14\u00b0<\/strong> horizontally and <strong>14\u00b0<\/strong> vertically, maximizing signal concentration in the target direction. This patch antenna requires precise aiming, as allowable off-axis deviation is significantly smaller than on models with a wider beam pattern. Focusing radiation into a narrow beam enables effective long-range signal transmission.<\/p>\n<p data-path-to-node=\"3\">In practice, a narrow radiation pattern means operating within a strictly defined sector in front of the antenna. For stable communication, accurate target tracking is required, as off-axis deviation results in a sharp drop in signal level.<\/p>\n<p data-path-to-node=\"3\">The 2.8 GHz 21 <span style=\"font-weight: 400;\">dBi <\/span>patch antenna measures <strong>450 \u00d7 420 \u00d7 23 mm<\/strong> and weighs <strong>1410 g<\/strong>.
