Newer and Cheaper Amateur Radio Telescope

The Horn Antenna seems to be a favorite goto and for good reason.

All you need is Aluminum flashing 20″x10, a empty paint thinner can, aluminized HVAC tape, N-to-SMA adapter, N Connector, Nooelec SDR and LNA. The cost would be roughly around $100.

The software can be either HDSDR or SDR#.

Will update after making this myself and testing it. More to come…

To build your own Amateur Radio Telescope, you will need a few item to get started.

You will need:

Antenna --> LNA --> Bandpass filter --> Power Injector (Bias Tee) --> SDR Dongle --> PC

Software used can be SDR# or a selection from https://www.rtl-sdr.com/big-list-rtl-sdr-supported-software/ ,

also need to download Radio Eyes to capture a Bell curve like the one below.
