The link to the second article wasn't on the page (yet)... here it is.

It contains a link to a spreadsheet for building up your own G/T model

Lowest NF

I am wanting to buy some receive preamps and am wondering if I'm looking at
it the correct way. Here are two examples from two different manufacturers,
both for the same band.

#1) .55dB NF, 16dB gain
#2) .9dB NF, 20dB gain

So, do you go for more gain or less NF? Since this is for weak signal
VHF/UHF work, I would say go for less NF but you can tell me what you think.
