There's an article in the October 2007 QST by Steve Ford entitled "Waiting
for the Sun". For those of you who read the article, and may have some
information/answers, I have a few questions regarding the construction of
the 160 meter inverted L antenna that is shown in Figure 3 of the article:
* Do I understand correctly, that C1 in the diagram is a simple
variable capacitor that ranges from 100 pF to 800 pF? (I found one, and
* Is it for tuning the antenna for minimal SWR?
* How did the author arrive at the wire length of 165 to 175 feet?
I know these are pretty basic issues/questions, but I built this antenna
today. I want to be sure I've built it correctly, and moreover, I want to
be sure I understand how to tune it correctly.
* Right now, I can get a minimal SWR of 3:1 at 1.810 MHz by tuning the
variable capacitor for min SWR.
* I don't have any radials installed at present. The coax braid is
grounded to my tower ground (three 8 ft rods bonded together)
* I plan on adding some radials (laid on the ground) tomorrow. Should
they be of any particular length to perform optimally?
I've emailed Steve Ford addressing the above, but I also wanted to see what
the folks at TT think.
