An active distributor allows you to use one antenna with multiple radios, without incurring any distribution losses, which for passive splitters are typically at least 3dB per split. It does this by using an amplifier before the splitter. This is especially useful if you have a wideband antenna like a Discone.<\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-49978 aligncenter\" src=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-083344.jpg\" alt=\"\" width=\"347\" height=\"325\" \/>The product comes with a built in battery, or it can also be powered via USB-C. Unfortunately it has a rather restrictive frequency range, only covering 100 kHz to 300 MHz.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-49973 aligncenter\" src=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082623-800x403.jpg\" alt=\"\" width=\"800\" height=\"403\" srcset=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082623-800x403.jpg 800w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082623-1024x516.jpg 1024w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082623-768x387.jpg 768w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082623.jpg 1059w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-49972 aligncenter\" src=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082744-800x486.jpg\" alt=\"\" width=\"800\" height=\"486\" srcset=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082744-800x486.jpg 800w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082744-768x467.jpg 768w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-16-082744.jpg 852w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<p>Source (<a href=\"https:\/\/www.rtl-sdr.com\/\" target=\"_blank\" rel=\"noopener\">rtl-sdr.com<\/a>)<\/p>\n<p>Purchase here: <a href=\"https:\/\/www.banggood.com\/Active-RF-Isolation-Distributor-Suitable-for-RF-Signal-Radio-Antenna-SDR-GPSDO-Signal-Source-p-1999743.html?warehouse=CN&amp;ID=0&amp;p=HP080535844950201908&amp;custlinkid=3579917&amp;cur_warehouse=CN\" target=\"_blank\" rel=\"noopener\">LINK 1<\/a> | <a href=\"https:\/\/de.aliexpress.com\/item\/1005006176427325.html?aff_fcid=f080e534c1e642f8b06813217bce4d5e-1700119816717-08342-_DBaaco3&amp;tt=CPS_NORMAL&amp;aff_fsk=_DBaaco3&amp;aff_platform=shareComponent-detail&amp;sk=_DBaaco3&amp;aff_trace_key=f080e534c1e642f8b06813217bce4d5e-1700119816717-08342-_DBaaco3&amp;terminal_id=0f877ea75c494ad5b76e170b8c85c077&amp;afSmartRedirect=y\" target=\"_blank\" rel=\"noopener\">LINK 2<\/a><\/p>\n<p>Estimate price: \u20ac22<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ONE ANTENNA FOUR RECEIVERS WITH AN ACTIVE DISTRIBUTOR Over on his TechMinds YouTube channel, Matt has uploaded a video where he reviews a US$20 active antenna distributor that he purchased on Banggood \/ Aliexpress.
