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?
