I wish that were my backyard! That's the lot to the street...so I put up a
mast at one end of my attached garage to hold one end of the antenna. Hope
the neighbors like it :).

Greetings Antenna Mavens --
In my bailiwick, it is common for those working 160 m to use a long sloping
wire with a particularly long loading coil. Many use a 70 foot straight
wire to or from a 70 foot wrapped loading coil - sometimes mounted as a
single sloper worked against a tower, or as a dipole.
Some put the loading coil up close to the feed point, while others put the
loading coil at the far end, like at the far ends of a dipole, or
the bottom of the sloper. I have heretofore considered this a huge
loading coil, and they tell me that it resonates well because of the length
of the wire. I've always been skeptical of the real value of the loading
coil, but they swear by these things.
Would anything like this help in this case, considering the poster has such
a relatively short backyard area. I'm interested in the answer, myself,
because I have an even smaller backyard than he does, and would also like to
work 160 on a better antenna that I have now.
Any traction?

Happy Trails.
