Folks,
Hopefully I've answered all the direct emails to me regarding this
and if I missed someone, my apologies, I have been having multiple
Blue Screens over the last week. I deleted several recent updates and
so far it seems like all is working properly.
As to my question; I'll order the tubing from DXE and will make the
elements 23' tall.
I do have a bugger of a problem to deal with though; where I need to
put this antenna is unfortunately dead on a pile of rocks that extend
a very long way and they are only a few inches below ground. I put up
a K9AY in that area and I had to try at least 10 times to find a
place to pound in a 4' ground rod most of the way down and even then,
I had about a foot left to go when I hit stone and the rod started
bending.
Since it is critical the elements be placed in the proper positions,
I've given it a lot of thought and am leaning towards fastening two
boards in a + pattern, figuring some way of anchoring the antenna to
the center and putting rocks on each leg to hold it in place in the
winds on the coast and put screen underneath to act as a capacitively
coupled ground.
If anyone has a better mousetrap, do let me know.
Thanks again for the suggestions as to antenna height.
73,
Gary
