My primary antenna is a 33 ft folded dipole made from 300 ohm twin lead and
is mounted in my roof. It is coupled by a 300 to 75 ohm tv transformer to
75 ohm coax. The antenna is described in message 2471 of the Yahoo Rx-320
group and works fairly well.

Recently, I acquired 3 rolls (40 ft each) of indoor 300 ohm coax, a closeout
at Radio Shack. On checking my house diagram (drawing), I determined that I
could run another antenna which could run about 100 feet if I include my
garage. This is measured from left rear roof, through a wall, diagonally to
front right garage (plus a 20 ft wrap on each end).

I'd welcome any suggestions from the group on an antenna configuration such
as dipole, folded dipole, twinlead converted to long wire (doubled back on
itself), etc. This would be for SW reception, but MW would be a plus.
Thanks.

Forget about using the 300 ohm coax. Do yourself a favor if you want
good receiving antenna. Go to Home Depot and purchase a roll of 14
gauge insulated wire, some screw-type eye bolts and two copper
plating ground rods and quad shielded RG-6 coax. Then build an
EWE antenna. It is one of the quietest antenna you can construct.
And has fantastic results. Check the web for them.

As for building an EWE, you are only partially correct about cut for
one or two bands.
If you modify some of the properties of the construction. You can
extend it's range.
I am usre most of the articles you have read state dimension such as
10 feet in
height by 50 to 80 feet in length. And yes if you keep at one
directional point it
does restrict reception based in it's orientation.

By using a fence in the backyard. I have an EWE that is 5 feet in
height by 180 feet in length. Wrapping all the way around the backyard
fence. Running N-S, E-W and S-N. Attached at the termination point for
the lead in coax, RG-6 Quad shielded burial type to a 16:1 balun.
Between the ground rods for each end. From a terminal strip I have
placed a ferrite core. Wrapped the 14 gauge insulated four times then
terminating the ground rod.

The second EWE is 5 feet by 40 feet orientated N-S. It has been
terminated to
ICE 180. This mostly used if the signals are strong, versus the other
for very
weak stations.

Unless the band conditions are at major storm levels,
propogation-wise. Or there are local thunderstorms. I have no static
build-up on either antenna. Which is a problem with other types of
wire antennas. There is far more flexibility with this arrangement.

Having tried dipoles, end-terminated, slopers and active antennas. The
EWE out
performs each of the above. They pull stations out of the noise the
others mentioned can not even lock on to.

Keep in mind that this type of antenna is somewhat in between a loop
and beverage type antenna. As for the comment about EWE in an attic.
Why not, you could still take the ends out the ground rods. It is
certainly feasible.
