Jim,
It will be interesting to see what others say but my take on this is that the
tuner function is to provide an impedance match
to the vertical and doesnt provide any choking. You still should have the
choke.

Those would be transmitted signal strength concerns.
On the receive side, if one ever listens on one's transmit antenna, the
feed coax shield is a potential path for RF noise from the house. Any noise
voltage allowed to go from the coax shield to the radials becomes a
differential voltage versus

First and foremost, I agree we need only to concentrate on 160 - 10, however
there is perhaps a way to incorporate
some limited activity on these bands (60 and 6 meters). As far as I am
concerned, 60M is a waste of time as it does
not count for DXCC, 6M counts. If marketed some limited

I have an LDG Z11ProII autotuner right at the base of my vertical - I did add a
common choke at the input to the autotuner (21' of my

The K3 does not operate on 6M,
The K3 is an excellent 6M radio. It's only shortcoming is that it needs
a preamp for 6M, and Elecraft has long sold one as an accessory. A new
improved preamp is standard with the new K3S. My KPA500 puts out more
I agree. We really don't want the coax shield to be part of the antenna,
regardless of whether the antenna is vertical or horizontal. If the coax
shield is part of the antenna, it can seriously distort the resonance and
the driving point impedance - hence the need for some common-mode
