Topband: BOG questions

[Artek Manuals]

I am in the process of experimenting with an RBOG .. I have seen in 
several places that  BOGS are "self-terminating" and as such have an 
optimum length (on 160M) of something on the order of 200-250 feet. 
Longer BOGs supposedly have degraded directional properties for lengths 
shorter and longer than this.

How important is matching the feed point impedance? I am led to believe 
that this can vary widely  with BOG "installation". Main installation 
Factors being; soil conductivity and ground placement ( in ground, on 
ground. on grass, etc). re there other factors to consider?

How would I go about "measuring" (not modeling !!)  the self terminating 
length for my given conditions. N/S I am limited to 200'  but E/W i can 
go up to 350'.

Finally though technically not a topband question. How "directional is a 
typical 200' BOG on 80 & 40? Or is an 80M BOG ideally 100' long and at 
200' the directional capability is degraded?
