[Moon-net] Orthogonal polarization???

There are a number of antennas that display this characteristic during 
array modelling.....whether they actually realise the result in the real 
world would be difficult/impossible to verify on an amateur range.

It happens 'typically' in some older designs that were not computer 
optimised, the old Tonna 16/17 can be easily made to display this if anyone 
wants to play with it..... I forget the stacking parameters that give 
this > 6dB result.

It occurs because coupling of the antennas together in an array has 
influence on  each part of the array.

But one has to be careful because poor segmentation can also distort 
results, either way,  as can 'short cut' modellers ( such as YO)  and the 
most popular g/t  modeller ( yagi 3.54) which has a 3dB 'assumed' gain in 
one plane also....
