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.
