If this is a program to share how about putting it on the web site files ? looks interesting to me also.

I don't know if it's still on the web site, but Decibel used to have a
simple DOS program that modeled the side-mount pattern of omnis at various
spacings and different antenna mounting orientations (like off the apex of a
leg, off a leg parallel to the face, off the center of a face, etc.).  While
it was OK for small-faced towers, it's not great for larger towers where the
horizontal and diagonal members start to behave like parasitic radiators,
converting the Vpol radiation to slant and horizontal pol.  I have a copy of
it somewhere if anyone wants it, just have to find it...

Hi Jim, 

I have a commercial information/guide sheet, which shows the 
various tower mounting layouts. I brought it in to work to 
scan and send to mike for the rb web page. I'll do that now. 

Anyone who would like a pdf copy of the Tower Mounting 
Guidelines Page, please drop me an email or wait for mike to 
get the copy I'll send him up on the rb pages. 

Again, please reply direct to me via email, not through the 
yahoo group. 

cheers,
skipp

Is there a recommended distance from the leg of the tower 
      
that a       
    
2-meter or 440 MHz Antenna should be mounted? I am going to have a 
couple of Antenna Mounts welded up and I wondering if they 
      
should be a
    
1/4 or 1/2 wave from the tower leg or possibly an odd multiple? TIA
