just wanted to say thanks to the many posters , i learned alot about
coax in general and thanks to a few posters i somehow 'got it'... and
started to see why a little al where the cu used to be like for like
didn't make as dramatic a diff as my untrained gut assumed it would,
dunno why i was so bothered by it bad assumption

thanks for all the facts , from what i learned unless i can see that
the outer jacket is soooo much better about keeping the elements out
i'd be concerned about using al but for inside runs it could save
alot of money and be just as good

usually the smallest coax i use is like lmr600/cinta600 and some
other variants some are all copper some are plated


i use it for both hf and naturally 2m/440 for higher i use lmr900
or heliax 1" it's very heavy 100ft to roof 100ft indoor runs stiff
and $$ so naturally i was attracted to the al coax but didn't want to
suffer losses or other al related problems


if corrosian is the the big killer i ponder even say for a indoor 2ft al
patch cable, how long that would last say compared to a coax copper
equivlant , i have really really old patch cables that still measure
good

i'll be interested to see some real world long term testing of this
stuff but seems to be sexy





thanks everybody


I have some al that has been up since summer 1990 with no problems. It has
actually held up better than the run of RG213 I put up the following year.
