[TowerTalk] 40M Beam Interaction

[Brian Harris]

Gale,

My XM-240 is 10' above and parallel with my TH6.  The SWR of the TH6 was not 
effected much on 20 and 10 meters (compared to measured values when it was 
pointed straight up).  15 meters is another story.  While the SWR was at a 
minimum at about 21.20 (when pointed up), 20.9 is where the current minimum is. 

Unfortunately both antennas were installed at the same time so I have no easy 
way of comparing other parametric changes.

Brian

I have heard that the "new" Cushcraft, 2 el 40M beam (XM240)  has
substantial interaction with nearby 20 M, full size, elements.  I
understand that the older 40-2CD doesn't exhibit this tendency!  Anyone
have any practical experience with these antennas stacked 9 - 12 with a
20 M beam?  Any info appreciated!
