The use of aluminum cable seemed to became popular when the cost of
copper was sky high. It became cost effective for some companies
(according to the bean counters) to use aluminum. Supply of copper was
beginning to become a problem, so some coax manufacturers were promoting
aluminum as a

Aluminum hardline was once banned at one mountaintop site I rent from.

The Andrew connectors came with a small tube of grease, presumably
silicon, that was to be used only on the O rings. Some of the newer
connectors seem to come with no grease. I don't remember having a
hardline connector seize up, except if it had serious water
contamination. In that case,
It's what Andrew calls Heliax 2.0 AVA, Andrew Virtual Air and AVAL Andrew
Virtual Air Aluminum. They are using a new lower density foam and thinner
copper to get slightly improved attenuation. Stay away from the aluminum stuff,
the corrugated shield is too thin and brittle. It's hard to

When you're pricing out 440 feet of coax, the pennies add up
to quite a
few dollars.
Depends on how you look at it. The difference becomes insignificant when
you look at the big picture. The price of 440 feet of line is a small
fraction of the total project cost once you add in
Andrews LDF4:
Any thought, comments about L4TNF-PS vs L4PNF-RC? -RC is a captivated
pin connector which is gold and silver, the other connector is bronze
inner, trimetal housing.
I'm thinking that the less potential metal interaction, the longer the
coax will last.
I've also seen Trilogy

The connectors should be fine, I wouldn't trust the aluminum feedline. You
may want to try using an anti-oxidation compound, such as No-Ox or Aluminum
Ox-Gard during assembly.

I'll have to ask a cable guy what they do, but all of the connectors
for the aluminum hardline I have seen are aluminum as are the housings
of the amplifiers, so the dissimilar metals issue does not exist 95%
of the time in the cable TV world.
In the RF world that is another story, I just took
