  1. N-type socket / female N-P245 instrument flanged RF connector, for soldering, extended dielectric, 50 ohms

    The N-Type connector was developed in 1940 at Bell Labs by Paul Neill, and the" N " in the connector's name appeared due to the first letter of his last name. Initially, the connector was developed for frequencies up to 1 Gigahertz, but later its potential for use was revealed at very high frequencies reaching 11 GHz, and thanks to the subsequent refinement by Julius Botka of Hewlett-Packard, the connector was used in systems operating at frequencies up to 18 GHz and can rightfully share the glory of one of the most popular devices in the world today. the most common high - frequency connectors with its predecessor-UHF. The connector has not found much recognition among radio amateurs and civilian users, but it has gained constant popularity among professionals and is used in mobile communication infrastructure, wireless data transmission (WiFi), paging and cellular communication systems, as well as in cable TV networks, standardized according to the MIL-C-39012 protocols.

    Help me choose a 450MHz omnidirectional, compact FR4 or collinear antenna.

    Can you post technical details for your antenna...???

    ,,,possibly CST-file....??!!!
