Coaxial lines it is not just RG-213 or 8's, is it? ¿what about hard
lines? (suppose a one with its ends absolutely sealed).

That would almost certainly be efficient and effective. Most Hams though
tend to be fairly frugal. Frugality and sealed hardline are not compatible.

No quite true. You can get free hardline form almost any cable TV
installer. That is about I all I use. No degradation at all. CATV
connectors are very water tight.

Are the connectors also free?

Dear Cecil:

For us, in Argentina, the 75 ohms 3/4" "free tails" hard lines from
CATV installers, are great for VHF & UHF. Imported 50 ohms HL are very
expensive, and now RG-213 too (3 U$D/m) (and paymento for our jobs are
relative low in international currencies).

I have seen nice "plumbers delight" cheap and simple home made
connectors in a website (I try find its URL).

I don't know how many time its dielectric conserves its integrity but I
suppose it is more that a RG-8 survives in the atmospheric real
sonditions.

Here's what I used for 3/4".

1/2" is really simple as it only takes a PL259 and a brass tube
coupling.

Normally you only seal one end of the line. That is to prevent the
line from developing a light vacuum when it gets cold or high
barometric pressure.
