Does any one have any ideas to what could be the cause of this?


Hi David,

Possibly because your feed point is not choked enough.

Hi Richard

I read on the internet, if I use 5x FT-140-43 rings stacked and then loop
the coax through 6 times it would make a good 1:1 choke balun. What do you
think about this type of choke balun for the job?
