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.
