        And the 60's, 70's, 80's,  etc. into the 21st century. Our antenna 
comparison reports used on-the-air  comparisons to a dipole for *real* 
results. Force 12 and SteppIR are 2  manufacturers that use our protocol in 
their 
published gain figures so they are  relatively comparable to our test 
results. The rest are in the YMMV category.
