Use the very best 50 ohm coax you can afford.

Well, in your previous post you stated that "You will hardly notice any loss..."

That implies that one WILL notice...

Loser! You should quote correctly -not destroying the content- 'tard.
A 50 ohm AirComm-plus cable costs three times as much as a lowloss 75
ohm TV-cable with the same loss.
And it gives pretty much the same results -if not better- on a broadband
antenna like a discone on consumer grade VHF/UHF-receivers wich do not
have a straight 50-ohm impedance. In most cases it varies between 30 and
150 ohms depending on the frequency you are receiving. So there is a
good chance a 75 ohm cable works even better than a 50 ohm cable with
the same loss. In worst case you will have an impedance mismatch loss of
3dB, but in most cases you will have a 3dB win depending on the scanner
you are using and frequency you are receiving.
There are few scannists who would buy or can afford a 0,70 US$/ft cable
for a 100ft run. So a good (lowloss!) TV-cable is really worth a try.
