Title: LNA for 1680 MHz sonde reception
Post by: w5cdt on May 14, 2013, 2335 UTC
In addition to the Radio Shack in-line satellite amplifer (Catalog #: 16-2565 ) with provides 15dB of 1680 MHz gain with a 3dB noise figure I also use the following product from Mini Circuits.  It runs nicely from three AA batteries and provides over twice the gain in dB. It also has SMA connectors instead of the F connectors found on the Radio Shack amplifer.
