A couple of weeks ago there were a lot of postings about my portable flag for radio direction finding (for tracking down RFI), and someone asked about the DX Engineering preamp that was designed for use with my portable flag and specifically what the noise figure was for this preamp. Tim (K3LR) said DX Engineering would measure it, and today he reported it measured 4.5 dB.
Tim mentioned that there were trade offs in the design such as low current draw and high gain, so the 4.5 dB noise figure is certainly unreasonable. It really is the only preamp I now use with my portable flag, and very pleased with how it works.
