check out the Balun One Nine v2. all you need to do is add wire depending on what frequency your after. fun place to start imo
​
I did a bunch of research. I decided to go with a Balun One Nine (https://www.amazon.com/dp/B08HGSYB7R/ref=cm_sw_r_apan_glt_i_5Y3XBC02WNN2DMY5GRA5?_encoding=UTF8&psc=1) and 16 awg wire. I ran the wire from the 2nd story of my house (my Ham stuff is in my office on the 2nd story) and down to our shed, which was 100ft. I ran the ground to a grounding post I have. I'm able to pick up an extremely broad spectrum with success. I have a Ham It Up upconverter but I haven't been using it, as I use Direct Sampeling on my RTF-SDR instead. I run OpenWebRX.
