Since 2024 a „Mini Whip Active Antenna“. Planned to be replaced with an Eggbeater antenna in 2025, which has a lower noise floor compared to the Mini Whip, it is located on the side of the building, it's best exposition is along the North South axis.

The Eggbeater Satellite Antenna has a Ground Plane and is resonant on 70 cm. We have tested it and has proven itself to be a great omnidirectional base station antenna receiving antenna for all Amateur Radio, Broadcast bands and many services. The ground plane elements under the Eggbeater increases the overall upward gain of the antenna, useful for hearing Satellites and the International Space Station.

DIAMOND MX-62M Diplexer for the ranges between 1.6 MHz and 56 MHz, and between 76MHz and 470 MHz. Allows to connect one antenna to two receivers.

The diplexer limits the optimal ranges of the SDRs to an overall smaller bandwidth, this limitation can be overcome by bypassing the diplexer for the required time, at the cost of using one SDR at a time.

It comes with a GPS Antenna for precise timing. The KiwiSDR is a software-defined radio that attaches to a Seeed BeagleBone Green (BBG) embedded computer. It is a standalone device that allows access through LAN and optionally through the Internet.

OpenWebRX is a multi-user SDR receiver that can be operated from any web browser without the need for any additional client software. Requires a computer, an SDR device and network access.

OpenWebRX is designed for public shared access.
