I am located in Westerham, Kent and have a good view of the sky from the south-east to the west.

I just use a basic antenna for this with no LNA. It is in a horizontal configuration and positioned in the loft space, which may be why I tend to get a weaker signal. I have a couple of other types of antenna, located in better positions, that I use for other radio astronomy projects. One of which uses an LNA module for hydrogen line applications.

As far as non-meteor events are concerned, the software removes signals that don’t contain at least one frequency near an estimated reference-frequency, hopefully keeping the meteor echoes. Its, not perfect though. I will have to try any determine what percentage of signal are actually removed.
