Specifically designed for commercial land mobile radio, public safety, and specialized UHF communications, this antenna delivers outstanding signal propagation and mechanical durability. The lower base section terminates in a standard MP (PL-259 compatible male profile) RF connector, facilitating a direct, vibration-resistant connection to standard heavy-duty vehicle mounts.<\/p>\n<p>The electrical design of the MC203B features a highly efficient 2 x 5\/8 wave collinear configuration. This stacked element design compresses the radiation pattern toward the horizon to achieve a high gain of 5.5 dB, significantly boosting transmission range and reception clarity in challenging mobile environments. It supports high-power mobile transceivers with a maximum power rating of up to 200W. Physically, the antenna has an adjustable length ranging from 86 cm to 97 cm for precise frequency trimming and tunes, while maintaining a sleek, lightweight profile of only 210 g to minimize mechanical strain on your vehicle&#8217;s mounting bracket.<\/p>\n<h2>Key Features<\/h2>\n<ul>\n<li>Optimized UHF mobile operation across the 460-490 MHz frequency spectrum.<\/li>\n<li>High-efficiency 2x 5\/8 wave collinear structure providing a substantial 5.5 dB of gain.<\/li>\n<li>Supports high-power mobile transceiver installations with up to 200W power handling.<\/li>\n<li>Standard MP base connector for seamless integration with standard mobile coaxial mounts.<\/li>\n<li>Lightweight and aerodynamic design to prevent mast deflection at highway speeds.<\/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;\">MC203B<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Antenna Type<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">UHF Mobile Antenna<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Operating Frequencies<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">460 &#8211; 490 MHz<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Electrical System Type<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">2 x 5\/8 wave<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">System Gain Metric<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">5.5 dB<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Maximum Power Rating<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">200 W<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Base Connector Type<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">MP (PL-259 compatible male profile)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Total Length<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">86 &#8211; 97 cm (adjustable\/tunable)<\/td>\n<\/tr>\n<tr style=\"background-color: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #dddddd; font-weight: bold;\">Net Weight<\/td>\n<td style=\"padding: 10px; border: 1px solid #dddddd;\">210 g<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Package Content<\/h2>\n<ul>\n<li>1x Diamond MC203B UHF Mobile Antenna Whip Assembly<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>UHF mobile antenna<\/p>\n","protected":false},"featured_media":21821,"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":[12331,12390,12324],"product_tag":[],"class_list":{"0":"post-13637","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-diamond-antenna-en","7":"product_cat-diamond-antenas-en","8":"product_cat-mobile-monoband","9":"product_cat-antenas-en-2","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"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 MC203B UHF Mobile Antenna | Commercial Radio Stock<\/title>\n<meta name=\"description\" content=\"B2B trade supply of the Diamond MC203B UHF mobile antenna.
