With all apologies to Joyce Kilmer! I think that I shall
never see a poem lovely as an antenna. ? Be it ham, commercial or
military, they are beautiful as can be to me. Be it a Ringo Dipole, Quad
or Yagi, they are all lovely as a tree. (???) I love them hidden
in the trees and out in the open. I love them on a chimney mount
or tower. What ever, whose ever, and where ever they are. I love
yours and mine, his and hers. What I really love (and this might
sound like a fetish) is porcelain insulators. There it's out, I prefer
them to plastic, which I feel is just a fad! I like to build antennas
without insulators, (tubing) I use shorted quarter wavelength stubs for
support. My favorite material is copper. In wire antennas I prefer
coperweld, which is technical for copper coated steel. The only problem
is when you buy it is in a coil and it is a coil ever more. If you
ever take the antenna down, it will wrap around you like an anaconda, if
you let it. The trick to removing the curl is to pull it between
two, two by fours bolted together and stuck behind two trees (or a fork)
and pull the wire through the boards with a car or a golf cart. (or what
ever?) Some one should un-spool the coil as it goes, to prevent a
kink from forming. For tubing antennae I prefer copper plumbing tubing.
I prefer the « inch rigid trade size, which is .61 inches in outside
diameter. I use silver solder which is truly a braze welding rod.
It is made of 5% silver, 1% phosphorus and 84% copper. The other
two ingredients lower the melting temperature. (there is a `no silver'
type that is a lot cheaper) The solder's 1,750ø melting temperature
anneals the tubing, which is technical for soften, so it becomes weaker
in the heated area, but if you use a plumbing fitting like a `T' or `el',
which I prefer not to, (because they take up too much length to make the
turn. etc.) the added thickness reduces the possibility of breaking or
bending. I cut short sections and slightly flatten them a bit and
butt silver solder the pieces together instead of using the plumbing fittings.
When I make wire antennae I cut the wire about four feet too long and I
loop the end through the end insulators and back toward the center insulator
and secure it there (at the calculated length) with a electrical fitting
called a "split bolt." Other than costing over a dollar each they
fit the need perfectly. I can slide the split bolt back and fourth
to "fine tune" the antenna. I even changed my 20 meter into a 15 meter
antenna this way. I think the loop at the end increases the bandwidth as
a bonus! I usually use a pair of split bolts at the center insulator,
because I change between an insulator and a balun sometimes. (to change
whether I have feed line radiation or not, when I want to add vertical
radiation to the horizontal radiation or not. If any one can tell
me where I could find baluns made in porcelain (or glass) containers, I
would be grateful, I have not been able to find any . . . But only God
can make a tree.
