Default I hate to say it but there sure is a bunch of ignorance here concerning VHF antennas

RG-213 is similar to RG-142, except you can find it for 70 cents a
foot. Mil spec and everything! Rated for both direct burial
(waterproof) and UV exposure.


Hi, Salty,

I didn't find, in my looking, any 213 MilSpec - can you give me a link?

However, and significantly, I did find that 213 is 2.8 vs 400's 1.5 loss on
the 150mHz band - and, much worse, of course, are the 8x at 4.7. 9913 is
only 1.7, and I can't put my hands on 142's at the moment...

Meanwhile, I've been seeing reference to copperplated aluminum center
conductors, or copper tube (on the monster sizes), along with the solid and
stranded copper. I have some challenges with clad/plated, cuz if it doesn't
hold up well in soldering, then I'm trying to solder AL. Anyone have any RW
experience with this? I know that AL was used in some house wiring, due to
costs, with some disastrous (heating/expansion-contraction) results in some
cases. Should I be nervous about this, or does the much higher copper melt
temp make this a non-issue for soldering?

Thanks for all the inputs. I'm slow, but I'm learning :{))
