[TowerTalk] JK C3S WARC Modifications

[Max Cotton]

I have a C3SS and it works to a fashion on the WARC bands but you have to turn it 180 degrees from the signal, the swr is over 10:1 but I still manage to work most stations. (Also works very well on 6m).
Looking at the JK ants, 5 and 6 banders, they are very heavy structures in comparison to the original force 12's, mine is only 22lbs whereas the JK version is up around 60+lbs. I would like to add the warc bands proper to the C3SS but it will probably have a bunch of interactions and build issues, not to mention element collision on a windy day.

I would be interested in what you come up with Herb for the C3S.  I was thinking
about the same thing. I am learning EZNEC but have a long way to go to tackle
this design.  It's way above my pay grade.  hihi

I use the C3S on 24 and 18 with a tuner.  It works but not very well on these bands.
Not surprising, it isn't really designed for these bands.
