I am considering building the Louisiana loop shown in this month's QST.
It is basically an inverted delta loop. I don't know if I can model it
on EZNEC (I guess I can...but I've only progressed through a dipole or
two).
I actually intend to string it up among some trees in the backyard in a
sort of temporary fashion.
Realizing the directionality involved, I will aim it toward Asia over
Alaska.
Now, any caveats or recommendations or ? before I embark on my first
antenna build?
I don't at present even know the feedpoint impedance but I intend to use
RG8U for feedline if that's possible. There is no mention of an UNUN or
Balun in the article.
What do youse think? Thinks?

Well, here's something new...responding to my own post (sort of)
As I started to collect parts needed for this antenna, I realize that
lightweight aluminum tubing at 7/8, 3/4 and 5/8 inches is not available
from Loews.
What's a good local source for aluminum tubing?
If you can't find Aluminum, see if you can get emt conduit in lengths
that will work. (heavy)
Don't use Aluminum. Hams have been building Quads and Deltas for 60
years using bamboo or fibreglass, with the wire taped or ty-wrapped to
the bamboo (fishing pole). You can get the fibreglass from Maxgain if
you want to go that route.
If you are dead set on duplicating the Author, try Texas Towers, they
sell different lengths of Aluminum.
