KH30937F - Beijing KeHuan Century EMC Technology Co,.LTD

KH30937F log-periodic antenna (hereinafter referred to as KH30937F ) is a linearly polarized broadband receiving antenna with a working frequency of 30MHz~1GHz . KH30937F has excellent standing wave ratio characteristics, accurate feeding position, and the best phase relationship between each period on the base. The antenna gain is basically constant, thus ensuring that the antenna factor changes linearly and smoothly with the frequency, which is helpful for accurate difference calculation between each frequency point.

GPS/GNSS Antenna Signal Splitter 4-Way, TNC Female, IP67 Weatherproof, 1-2 GHz

GPS421

INSTOCK Wireless Components, Inc

GPS421 - INSTOCK Wireless Components, Inc

GPS421 is a four way, passive, GPS signal splitter ideal for splitting a GPS antenna signal between two receivers while providing a DC current path to power a remotely located active GPS antenna from one receiver while blocking the DC path from the other. Furnished with TNC female connectors all ports. A special feature of this unit is the 200 ohm internal load which provides a current drain for the GPS receiver not powering the active antenna. Some GPS receivers incorrectly sense an antenna fault when there is no current draw. The 200 ohm internal load provides a simulated antenna current drain which prevents receiver faulting. Max voltage rating at the DC blocked ports is 15 VDC; maximum current rating is 75 mA. Max voltage rating at the DC pass port is 50 VDC; max current rating is 2000 mA.
