Poor coax will attenuate - some frequencies more than others, but if the
antenna kicks out enough, it will not be an issue.

Your knowledge of this subject is lacking.

Poor coax unless its totally BROKEN and in high signal areas, will not
introduce ghosts or pickup MUCH in the way of noise and interference.

Rubbish. A kink or badly made off connector WILL intoduce reflections and
losses. Poor quality cable will also have poor impedance consistency, again
adding to the problem. Couple that with the increase in attenuation with
higher frequency and you have a recipe for disaster.

I do understand YOUR motivation to do every thing "cheap", but don't advise
others to waste their money in the same way please.

Good coax is better, but bad coax and a decent antenna beats good coax and
a piece of coat hanger any day

Not necessarily.
