Trying to improve my reception from Chicago with baseball season
approaching. I'm about 100 miles sse in Indiana. I ran about 75' RG-6
from
my radio across the attic and outdoors to a tree. I had maybe 10 extra
feet
of coax so I wrapped it around the tree. I strung about 50' of #9 steel
wire
between 2 trees going east/west about 15' above ground and attached the
copper conductor to it. I terminated the coax shield at the tree with a
ground rod. At the radio I attached the shield to the ground terminal
and
the center cu conductor to the other am external antenna terminal.
It greatly improved my reception I get all the major Chicago sports
channels, but the one I was most interested in 670 is the worst. What all
did I do wrong and what can I do to improve 670?
Try disconnecting the ground rod at the tree and connect
the braid of the coax to the antenna input. Ground the
radio.

Thanks for all the replies and help. I did try grounding at the radio but I
disconnected the shield at the radio not out at the outdoor connection. I'll
try Jitt's suggestion. I've goggled around on constructing a loop antenna
and it looks do-able for me so I may try that.
Most of the information I used to construct the long wire came from this
link
http://www.hard-core-dx.com/nordicdx...b/coupler.html
the
author also describes a coupler which I may attempt if I can scrounge the
parts unless anyone knows if something like that is available commercially.
Also could somebody recommend a lighting arrestor that would work with the
RG-6 male and female connectors where the long wire connects to the coax.
