[TowerTalk] R7 Mounted ontop of a triband yagi

[RLVZ at aol.com]

Hi Mark,
 
That's a great question!  I can't wait to hear what the guys  say as I'd like 
to try the same setup myself.  My gut  feeling is that since each antenna 
will have different polarization that you  won't need much separation between the 
two antennas. 
 
But I am thinking that you may need to insulate the vertical from the  
tower/mast in order to maintain reasonable SWR.  Otherwise, the whole  tower and 
tribander may load up as part of the antenna.  I've had this  problem when 
mounting verticals on metal masts before.

Hello  group, this time I am looking for help about the mounting of my R7 
above of my  old Triband yagi, At present I have my R7 mounted on top of  a mast 
which  extends out of the top of my tower by 7 feet, I would like to know if I 
were  to mount my ATB-34 Cushcraft triband yagi will I need more than the 7 
feet I  have available at this time? I have looked thru the manuals for both 
antennas  and there is no mention regarding a situation even similar to  mine...

So in short what would you folks suggest I use as a spacing  between the R7 
and the ATB-34...
