Here's the page I wrote years ago on the split-shield antenna:
http://www.febo.com/time-freq/wwvb/antenna/index.html
Unfortunately, I never took any photos and the antenna is now in pieces
after a couple of moves.
I've also had good luck using an active voltage probe antenna to receive
both WWVB and LORAN-C. The one I used was designed by the AMRAD group
(info at http://www.amrad.org/projects/lf/actant/).

Gents,
Wrote:< John's antenna should be in the archives. Just 100 feet of RG-58 wound
on a 4 foot diagonal PVC pipe frame, with the shield split at 50 feet, IIRC. Tried
resonating it, got unstable results.

Could you please elaborate on the construction details such as co-ax used,
indoors or out, and type of tuning caps used, ect? What was the input amp used?
I was planning on making that antenna but don’t want to go to all the effort
for a bust. My antenna would be outside and I plan on using some RG-6.

Perrier
