I haven't seen any products like this either. We're working on a product like this, but it's still a few months out. That's great news! Especially when RTL-SDR community more oriented to higher frequencies than HF - airband, satellite communication, ADS-B and so on. Can't wait so see what you, guys...

Hi everybody! I've already ordered differential HF loop antenna amplifier kit from RHelectronics I'm planing to build this kit and loop antenna for it. Just for learning and testing purposes. But since I have SDR, this antenna is not great for that purpose (narrow bandwidth). I'm still quite new in ...

Recently I've ordered differential HF loop antenna amplifier kit from RHelectronics This amplifier has very similar design as this one: http://www.techlib.com/electronics/graphics/loopantsch.gif Antenna tuning is done by MVAM115 varactor diode or varicap (instead of variable capacitor), by using mul...

Hi everybody! I'm quite new to SDR and especially radio-electronics related DIY. So I'm sorry for silly assumptions and questions. Currently I'm thinking to build HF active loop antenna, since I'm living in urban environment and I don't have lot of space for longwire/dipole or similar antenna. So......
