A friend gave me an unknown (to me) HF antenna.
Only marking on the 5 foot long white plastic pipe case is "Smithe
Antennas, Laurel, MD"
Inside the pipe are about 6 pieces of aluminum tubing , some 1/2 inch
white plastic pipe, one elbow, a plastic pipe T
with a small length of coax attached to a pair of "clips", and a set of
coils stuck in Styrofoam.

No paperwork.
Anyone familiar with this one?
