This is a new filter, designed for use with preamplified “probe” antennas, and many other receive antenna systems. This includes a bypassable low-frequency shelf filter, and can be jumper-configured for either 30 or 60 MHz low-pass anti-alias filtering.

And a new 60 MHz Filter-Preamp:

This one has an aggressive low-pass filter, optimized to eliminate 88-108 MHz FM broadcast band signals before they can cause trouble. The high dynamic range preamp provides about +20 dB of low-noise gain.
