Kevin, Kazaross has been the most active experimenting with BOGs.... for about the last two years. Most of his BOGs now tend to be in the 400 to 600 foot range, as I remember. However, I think that he started out at about 200 or maybe even less. Laying on the ground tends to make the thing act electrically longer, some folks think.... and being on the ground, the side lobes seem to be significantly reduced. I'd suggest that you run two coax lead-ins out to the common ending area, use impedance matchers and terminate the far ends as best you can.
Alla that said, BOGs naturally respond differently to different soil conditions, probably more so than air-suspended antennas. KAZ has about average soil conductivity, I've got very high here in central Oklahoma and yours is on the low side (I think) being near Puget Sound. I'm going to be trying the same thing here for some GY work... where I think that Less (antenna) may be More (DX).... the experiments may get done this spring, I hope. Let us know. If you don't have any impedance matchers, there is a nifty article at http://www.dxing.info/equipment/ called "A Second Look at Fabricating Impedance Transformers......" Look on the lower left of that web page. And, Kevin.... PLEASE let us know your results. As our hobby ages, a lot more of us are considering downsizing to condo's, garden homes, etc... and smaller antennas for the home place are in our futures. DOES ANYONE ELSE HAVE ANY DIRECT FIELD EXPERIENCE WITH 150 to 200 FOOT BOGs???? John B.
