I check the SWR on each one as I put it up, but I've never gone back and 
checked the SWR on antenna #1 after I've installed #2 or on #1 and #2 
after installing #3.

I have a file folder on my PC for each QSO party I do. I create the folder 
for next years the day I get back from the current year. One of the 
documents in that folder is a WORD document that I call "Things to think 
about for next year". I just added a note to remind me to check the SWR 
again on each antenna as another is installed; I also put in a note to 
comment on any interactions on the reflector next year. Presupposing, of 
course, I go portable next  year.

My gut feel is that, yes, there is some interaction. I say that because 
one of my antennas......the 40 cw I think, had a higher SWR on Saturday 
than (I think) it did on Thursday when I put it up. Though I do install 
the 4 CW as a flat top and the 40 phone as an inverted Vee. Not sure what, 
if any, impact that would have on any interaction.

I'll let you know next year.........hi hi....
