Subject: Re: Topband: BOG antennas
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.
