The charts on the SteppIR web page show forward gain and front to back all
across each band.
a 32 foot boom is probably too long for optimum on 10 and maybe 15. So far
don't see a parasitic element for 10 as with the KT 34/36XA and the XA works
great on 10...better than a 5 el KLM and almost as good as the 7El 10 I
built from the first issue of Ham Radio Magazine.
The charts are nearly as good as the final revised charts for the 34XA and
just less than the 36XA charts on the M2 web page (for 10 meters).
