Hello Bruce, 

This is a very interesting subject. 

I am about to "maybe" test a BOG here at my French QTH and I am wondering 
if there are any tests made with best terminating resistance (235ohm? ) 
should I use a 9:1 transformer or 10:1 ? 

how does it perform compared to a usuall beverage? 

Can I cross 2 BOGs for 2 directions or more? will this affect the antenna 
pattern? 

I recently built an W7IUV preamp, will it be OK for the BOG ? 

Thanks in advance.
