Comments:

I have almost zero experience with 160.  I live on a city lot and my antenna
farm competes for space with the kids swing set and playhouse in the backyard. 
I decided that I wanted to operate the 160 contests this winter so two weeks ago
I wound 265 feet of 14 gauge THHN wire around 24 feet of PVC pipe.  I got this
design idea from K6MM.  I topped the vertical with a 3 foot capacity hat made
with solid 14 gauge copper wire and 1/8 inch brass rods soldered together. 
This gave me about 20 khz of bandwidth at about 2:1 swr.  I made a loading coil
with about 14 or so turns of solid #14 wire around a 1.5 inch PVC pipe and
connected it between the antenna element and ground at the bottom.  That gave
me about 40 khz below 2:1 with the lowest at about 1.2:1. For radials I used my
existing radial field for my 40 meter vertical and 80 meter inverted L.  This is
70 or so radials ranging from about 25-60 feet long.  I also stripped out some
old cat 6 cable that I hadn't thrown away yet and added another 20 radials
around the base about 20 feet long.  Overall, the antenna looks so ugly that I
have a hard time admitting that I made it.  However, it was cheap and it worked
well enough to get me on 160 in a city lot.  I had some family conflicts so I
was only able to play for about 4 hours, but I was very surprised at how well
the antenna worked.  With 500 watts I was able to hold a run frequency without
too much trouble.  For a receive antenna I threw 140 feet of #14 wire on the
ground and used the MFJ-1026 noise canceling box.  I was very surprised at how
well this thing works.  Once you figure out how to use it, it is worth many
times its weight in gold.  

I had a great time this year.  Next year I will probably move the antenna and
try the 160 Meter FCP I keep reading about.  I just happen to already have the
correct toroids left over from another project.  

Thanks for the Q's.

73, Morgan, NS0R
