Highly regarded by telecommunication engineers and amateur radio operators alike, this precision-built power divider allows you to feed two stacked directive antennas in perfect phase. By combining two antennas, the FDVU-2S helps you achieve a narrower vertical radiation pattern and gain an additional 3 dB of system performance, dramatically extending your station&#8217;s reach and coverage.<\/p>\n<p>Built for demanding outdoor base station installations, the FDVU-2S features a rugged, weather-resistant aluminum and brass alloy housing designed to withstand extreme temperature fluctuations, high wind resistance, and corrosive environments. It terminates in premium, low-loss N-female connectors to ensure maximum impedance matching and signal integrity across high-frequency UHF bands. Its structural integrity ensures that insertion loss is kept to an absolute minimum, allowing you to maximize your effective radiated power (ERP).<\/p>\n<p>The unit features a pre-installed, heavy-duty mounting bracket designed to clamp directly to any standard antenna support mast with a diameter ranging from 30 to 62 mm. Measuring 54.5 x 7.0 cm and weighing a solid 1.1 kg, the Diamond FDVU-2S is engineered to balance physical strength with minimal wind loading, making it a highly reliable, long-lasting component of any high-performance directional antenna array.<\/p>\n<h2>Key Features<\/h2>\n<ul>\n<li>Dedicated co-phasing stack transformer designed for Diamond FDU-31 and FDU-11 antennas.<\/li>\n<li>Adds up to 3 dB of system gain by cleanly phasing and combining two directive antennas.<\/li>\n<li>Equipped with high-performance, low-loss N-female RF connectors for superior signal integrity.<\/li>\n<li>Rugged, weather-sealed metal housing engineered for long-term outdoor base station use.<\/li>\n<li>Heavy-duty integrated mounting bracket fits standard masts from 30 mm to 62 mm in diameter.<\/li>\n<li>Engineered to maintain a highly stable 50 Ohm impedance match with minimal insertion loss.<\/li>\n<\/ul>\n<h2>Technical Specifications<\/h2>\n<table style=\"width: 100%; border-collapse: collapse; font-family: sans-serif; font-size: 13px; text-align: left; margin-top: 15px; margin-bottom: 15px;\">\n<thead>\n<tr style=\"background-color: #f2f2f2; border-bottom: 2px solid #dddddd;\">\n<th style=\"padding: 10px; border: 1px solid #dddddd;\">Parameter<\/th>\n<th style=\"padding: 10px; border: 1px solid #dddddd;\">Specification<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Brand<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">Diamond Antenna<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Model Designation<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">FDVU-2S<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Product Type<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">RF Stack Transformer \/ 2-Way Co-Phasing Power Divider<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Antenna Compatibility<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">Diamond FDU-31, Diamond FDU-11 (or equivalent paired UHF antennas)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Connector Type<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">N-Type Female (Low-Loss)<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Nominal Impedance<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">50 Ohms<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Accepted Mast Diameter<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">30 \u2013 62 mm<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Physical Dimensions (LxW)<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">54.5 x 7.0 cm<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Net Weight<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">1.1 kg<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Package Content<\/h2>\n<ul>\n<li>1x Diamond FDVU-2S Stack Transformer<\/li>\n<li>1x Heavy-Duty Mast Mounting Bracket &amp; Hardware Kit<\/li>\n<li>1x User Reference \/ Assembly Instructions<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Stack Transformer<\/p>\n","protected":false},"featured_media":58359,"template":"","meta":{"_acf_changed":false,"_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","inline_featured_image":false,"_joinchat":[]},"product_brand":[12171],"product_cat":[12395,12324],"product_tag":[],"class_list":{"0":"post-58360","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-diamond-antenna-en","7":"product_cat-dipolos-hf-en","8":"product_cat-antenas-en-2","10":"first","11":"instock","12":"taxable","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Diamond FDVU-2S Stack Transformer | Antenna Power Divider<\/title>\n<meta name=\"description\" content=\"B2B trade supply of the Diamond FDVU-2S antenna stack transformer.
