[TowerTalk] M2 20M5 SWR

[john at kk9a.com]

Is the SWR OK higher in the band or bad all across.  If it is bad all over 
it is possible that the 10m boom is interacting.  I think that the Cushcraft 
elements are not insulated making it difficult to guess if there is any boom 
interaction without modeling the system. Why is the 10m antenna at 90 
degrees?  There should be little interaction if they are parallel and it is 
easier to operate the station when the rotators have the correct reading.

Hello,



I installed a M2 antenna, 20M5 at 33 mts.  I assembly it for FULL BAND
dimensions



I have in the same tower a stack of three XM510 monobanders for 10 mts, the
top one is 3 mts over the 20M5 cross at 90 degrees from the 20M5.



At 14000 I have 2.9:1



This will be because of the other 10 mts antennas in the same tower?  Or at
FULL BAND the 20M5 have this swr at 14000?



Thanks!



73,

Jorge
