Dave,That was my thoughts on it also. Two wires
very close togethether with in phase and more or
less equal currents just adds up to a fatter
wire.

Not a fatter wire with twice the current?

Recall the colinear J-pole, The two currents are stacked and fed in phase
by means of the phasing section. Yes, I realize the currents in the Slim
Jim would appear to cancel.

I'm going to have to build one of these and see what it does. I have a
lot
of twinlead and I have a precision RF generator. I always wanted my own
antenna range; tomorrow's the day. Maybe Tuesday.

Hi "Sal"

I share your thoughts about a pattern range. I recently talked my buddy
into writing a program that plots Elevation Plane patterns of an antenna
when scaled to a frequency sent from any Polar Orbiting Satellite. I use
it alot using the 137 MHz beacons sent from NOAA satellites. Some HAM
satellites could be used. There are also L-band beacons sent from the NOAA
satellites.
