Re: [amsat-bb] AO40 Downlink, RG213 verses 1/2 inch

["Gary \"Joe\" Mayfield" <gary_mayfield@xxxxxxxxxxx>]

Your noise figure and signal to noise ratio are pretty much made at the
downconverter.  I would be stunned if you have any improvement at all.  In
fact it may be counter productive depending on where your noise floor is
now.  Sometimes a little attenuation is a good thing.
