Hi JC,
I have just recently put in a BOG.
But before I installed the BOG, I ran my 240 feet of coaxial feedline
out to where I expected to put my BOG transformer.
I terminated the coax and connected the other end to my radio. I started
logging S units and frequency of all the AM stations I received.
I had about 13 stations with as high as 5.5 S units. I tried chokes
and transformers
and grounds without much reduction.
Then I ran a piece of twisted speaker wire out to the same position
and terminated it.
This had only 4 stations, 3 were at Zero S units but audible and one
ran close to 1 S unit.
The speaker wire is clearly the winner.
I may have done several things wrong. The speaker wire runs within 6"
of a chain link fence for
about 60 feet, it is on the ground the whole distance, it is probably
pvc insulation.
But I now have it connected to a 253ft BOG and it seems to be working
well compared to my
150 ft long wire. I test it on AM band stations and it is clearly the
better antenna,
it has a better Signal to Noise on almost every station.
