Helically wound multiband vertical antenna-portable in Poland



Walt (K4OGO) came up with this helically wound vertical antenna while he operated as SP/K4OGO in Poland.  

Other than a narrow bandwidth, this antenna provided multiband capability at a modest cost.  The key to this antenna design was the 9:1 balun used in the feed line.

Here are some comments from Walt (K4OGO):

I built a multiband helically wound vertical antenna from parts that I had with me in Poland. I had amazing results.
