[TowerTalk] klm kt34 help

[Norman J McSweyn]

Hi all, 
I'm in a quandry. My antenna swr has changed. The swr has increased on the whole of 20m. On 20, it is like the sweet spot is now above the band rather than where it should be. The other bands are different, too. 
changed:
new balun from m2
new feedline
The good news is that the antenna is on a 10ft section of tower on my (flat) roof. It'll be on the roof at 730 am.
Any Ideas????
tnx de n3ykf
