Remote RX antenna switch
- custom production -
This switch was made for Christoph OE2CRM. He is trying to catch the broadcast stations from all over the world at Medium Wave (MW) and Short Wave (SW). His remote QTH needed hardware to control all of his RX antennas including Bi-directional beverages, different RX loops, single wire beverages and also remote preamplifier boxes with power over coax placed in feed point of RX antenna.

This project has started in 2016 and used Remote manual IP SWITCH from RemoteQTH.com. After 5 years we upgraded IP Switching to Web-based one with much more features. Web-based relay box with Raspberry Pi 4 allows to control unlimited numbers of IP switches with customize lables, groups profiles. Switching can be done by web, mobile app or hardware switch keypad.
We designed web-based remote controlled 9 RX antenna switch with common-mode filters, preamplifiers and build-in bias tee. There is the possibility of use time scheduled switching for easy operation.
