"remove dipole"


sorry - habit... name is Gary, signed 'g.' and the call is K9RX.

Unfortunately I have a severe fear of heights so I can't easily 
pull the dipole out - and it is very difficult, actually most 
often impossible to find someone that can climb anymore. Thus I 
was hoping to have some evidence that would suggest which is the 
best plan.

I believe, after thinking about it, that the first section of 
guy wire which has an insulator at ~6' out is the problem. The 
top antenna shows very little effect on SWR on 10 and 15 - and 
its angle to the tower is greater... the middle is worse - the 
bottom is the worst. It would make some sense I would think 
that, since this section is tied directly to the tower - and 
thus a total of 13' long THROUGH the tower that this is coupling 
and re-radiating. The fact that there is very little effect when 
rotating the antenna leads me to believe this (as well as the 
swr effect). So I am thinking of working on the bottom antenna 
to see if I can change this - maybe try making the first section 
longer by adding a "stub" at the end of the section. I plan on 
setting a baseline comparison of the WARC dipole and the bottom 
beam - then change this and see what if any effect it has.
