Installed this nice RAMI AT-197A/GR Military Discone today. It’s a great broad band omni-directional antenna optimized for 225-400 MHz. Along with the antenna I am using a custom Angle Linear LNA with a NF of 0.7 and a gain of 20dB for the Military Air band 225-400 MHz.
Here is a sample of the audio from a recent intercept from some T38 jets on a training mission that didn’t go as planned.[audio:https://usa-satcom.com/wp-content/uploads/2012/09/mil-D12000Hz_20120308_0126091.mp3]
