This model is ideally suited for configurations operating in the <strong>2.4 GHz<\/strong> band. Thanks to its wide bandwidth, the antenna offers extended functionality when paired with receivers utilizing custom frequency bands.<\/p>\n<p data-path-to-node=\"6\">The FT K5 antenna covers the standard ExpressLRS 2.4 GHz band (2400\u20132500 MHz) while extending well beyond its limits. Featuring a standard <strong>IPEX1 (U.FL)<\/strong> connector, it is fully compatible with most ELRS 2.4 GHz RX receivers. Maximum performance is achieved when pairing the FT K5 with <a href=\"https:\/\/ft.systems\/en\/elrs-se4\/\">SE4<\/a> series receivers and custom-frequency firmware.<\/p>\n<p data-path-to-node=\"7\">The FT K5 features a gain of<strong> 2.0 \u00b1 0.5 dBi<\/strong>, linear polarization, and an omnidirectional radiation pattern in the horizontal plane with a vertical beamwidth of approximately <strong>65\u00b0<\/strong>. It is rated for<strong> 50 Ohm<\/strong> impedance and a maximum input power of up to<strong> 20 W<\/strong>. The radiator is made of <strong>\u00d8 2 mm<\/strong> brass wire, while the mount is crafted from durable molded plastic.<\/p>\n<p data-path-to-node=\"8\">The radiator length is <strong>158 mm<\/strong>, cable (feeder) length is <strong>180 mm<\/strong>, and total weight is <strong>7 g<\/strong>. Connection is established via an <strong>IPEX1 (U.FL)<\/strong> connector. Prior to installation, it is recommended to verify receiver operating frequency and connector compatibility.<\/p>\n<div style=\"display: flex; flex-wrap: wrap; align-items: baseline; max-width: 100%;\">\n<h3 style=\"margin: 0; margin-right: 5px; line-height: 0.8; max-width: 100%;\"><strong style=\"font-size: 16px;\">Manual &#038; Datasheet<\/strong><\/h3>\n<p><span style=\"font-size: 16px; font-weight: bold;\"> \u2014 <\/span><a style=\"font-size: 16px; font-weight: bold; line-height: 1.8;\" href=\"https:\/\/ft.systems\/wp-content\/uploads\/2025\/04\/FT_K-5.pdf\" target=\"_blank\" rel=\"noopener\">Download PDF<\/a>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>FT K5 broadband control antenna (2000\u20132700 MHz) with linear polarization for FPV systems, ELRS, and Gemini.
