KAZ replies, It seems Gil saved some of my BOG comments to him from last year, and everything I said then still applies now.
My shorter northern BOG is about 155 ft at 350 degrees and by itself is a reasonable antenna on the high end, with the beam being a bit too broad for my tastes on the low end, but still having OK side nulls. I terminated via a 270 ohm resistor to ground but it didn't seem as effective as the same termination on the longer northern BOG about 295 deg at 355 deg. Even without phasing that longer antenna beats anything else to the North and upper band regionals and GY's are filled with MN, WI, and upper Mich stations as well as Manitobans. When I phase the two, it is really nice as I can kill back end QRM. 73 KAZ Barrington IL Kevin, I also found this from Kaz: "My mini-Phased BOG System here is aimed 35 deg and is 341 ft // 214 feet and is stunning for TA's and also for East Tex/East Mex stuff. " These parallel bogs which are phased, are only separated by 2-3' . I modify what I said earlier about your ability to run one bog 300'. You could most likely run two parallel of different lengths.
