Dear OMs,

Via this newsgroup I learned that last September the following article
appeared in QST:

p.28: An Easy to Build, Dual-Band Collinear Antenna by Dan Friedrichs,
K0IPG

I am particularly interested in this article, because at this very moment I
am designing myself a 70cm colinear.
Unfortunately, I do not have access here to this article.

Before I contact the ARRL's reprint service, I was wondering if somebody of
this newsgroup who has read this article,
could brievely describe the basis principle of this antenna (coils?, phased
line?, electrical length?).

Many thanks!
