[TowerTalk] steppIR Gain--test method

[Jim Jarvis]

TT:

If I recall correctly, Mike and Jim have their own range,
with the unit under test on one tower, and an HP spectrum
analyser connected to a dipole on another tower,  many
wavelengths distant.  Tower heights were on the order of 
60'.  A calibrated attenuator was used with the SA.

The testing methodology was described on their website,
back when they sold me the 3 el, 3 years ago now.  

Comments regarding narrowbanded antennas, current,
drive point impedance and fwd gain, all noted.

Theoretically, the steppIR could be a bit better
than a canonical yagi...in practice, it's hard to tell,
because the differences are too small to matter.  
But it IS fun to talk about.
