[ICOM] G5RV Dipole

[D C Macdonald]

My suggestion would be to feed the two legs
together and connect the ground of the tuner
to an actual "ground."

I use a similar setup, but am not using an auto-tuner.
I feed my IC-746 through coax to an old Heathkit
Airwound balun under the eave of the house then
use ladder line to a center-fed dipole approximately
120 feet in length.  The auto-tuner in the 746 will
not handle this on 80/75 meters, but does fine on
40 meters and up.  On 80/75 meters I use a Ten-Tec
238 tuner which is an L-Matching system with a
roller coil and the capacitance switchable between
the input side and output side of the tuner.  It is
a tremendously versatile setup and I get zilch for
reflected power.

Hope you find a solution.

Hi all,
 
On 80m the only antenna I have is a G5RV dipole, rig is an IC756 Pro II. The
antenna will not load up directly. I also have an AH-9  auto antenna tuner.
On the G5RV dipole the open wire feeder terminates to an in line SL259
socket, here I connect some co-ax and at the AH-9 I twist the centre and
core of the co-ax together and feed the AH-9 directly. Is the right thing to
do?? Or would I be better off connecting one side of the dipole to the
antenna terminal of the AH-4 and the other side to earth??
 
Would appreciate any comments and advice…………
