Re: [IRCA] Shorter BOGs

["Neil Kazaross" <neilkaz@xxxxxxxxxxxxx>]

If I recall the zigzagged Bev is done in the vertical plane. I have read of 
couple hams who'd done that, and I don't recall them being terribly 
impressed or thinking it was worth the effort. I'd suspect that the vertical 
components would adversely effect the Bev pattern.

Now for a zigzag BOG on the ground, I suspect that it might act like no more 
than a bunch of small BOG's in series but aimed at least 90 degrees from 
each other and end up with a much broader beam and also very poor side 
nulls.

At some point I can try to model this in EZNEC but it will be a lot of work 
to type in for 100 wires or so.

I don't claim to know the answer here and I wish you the best of luck if you 
try it. I do recall about 6 years ago when I put down my first real BOG here 
in Barrington and my jaw dropped when I quickly realized how good it was. 
Many in the DX community were quite skeptical, but now BOG's are used all 
over the world to good effect. So....if you don't try...you don't know for 
sure.
