Review on Nooelec NESDR Smart v4 Bundle - High-Quality RTL-SDR with Aluminum Enclosure, 📻 Accurate 0.5PPM TCXO, SMA Input & 3 Antennas. RTL2832U & R820T2-Based Software Defined Radio. by David Tadder

Really liked it and paired it with a NooElec "Ham It Up" converter to receive signals below 25MHz. I am using the SDR Sharp software. which works very well. The three included antennas are basically useless unless you're sitting on a mountain with no other electrical equipment on top. There is a lot of electrical interference in a modern home. Almost every device, big or small, generates electrical noise. Even LED bulbs emit their own buzz. You need a good outdoor antenna in the attic or outdoors, powered by good quality coaxial cable. I've found that plain old RG-6 TV coaxial cable works very well. The "It Up" converter accepts signals below 25MHz and works best with a long wire antenna or tuned dipole that is as far away from household noise sources as possible. To do this you will need a 9:1 (or Unun) balun and match your antenna more closely to your receiver setup (this is easy to do - look it up on the internet). I bought one online but it didn't work at all (probably defective) so I wound up my own.
