I purchased the CrankIR, which is a manual version of the BigIR.  It is
shorter than the BigIR.  SteppIR claims it has a gain .3db lower than the
BigIR.  I got the 80 meter version, with carry bag (25"L X 8"W X 8"H).  I
use the YouKits FG-01 Analyzer to get precise SWR readings for the selected

This is a great alternative for portable use, either backpacking or
DXpedition.  It may be on the air in Aruba next year.

This is a much better antenna than the fixed height 43' vertical that is so

Jim. The bigIR can be tuned to a quarter wave on all frequencies from 7 to
54 MHZ. On frequencies from 21-54 MHz you can select a 3/4 wavelength mode.

I have used this antenna with raised radials, tuned stub radials and a
ground mounted radial field.  Works well in all cases.  It is still a
quarter wave vertical.
No magic
