In addition to coax traps there are two or three commercial
sources of traditional L/C traps - including the Reyco (W2VS)
KW75 and KW80 available through vendors like Amateur Electronic
Supply and Ham Radio Outlet.

The low trapped inverted V will be a "cloud warmer" and not
particularly efficient but it will be better than nothing.
It is certainly possible to work a substantial number of
stations - including more than 100 DXCC countries with an
80/160 M trapped dipole and 100W.

Coax traps are relatively easy to make.  Check out ON7EQ's website for more info

Hope this helps.

Hi all,

The ARRL 160 contest got me interested in 160.  I would like to add loading coils and 
additional wire to my 80M dipole at my QTH in Maine to see how that might fly.  (It would 
make it an 80/160 dipole.)  Yes – it won’t fly very well, and be narrow band, 
but it will be easy to do and better than nothing.  I have looked in the ARRL Antenna Book 
and Low Band DXing and have found little of help.  I do have one article from July 1992 QST 
by W8NX that looks to be helpful.

Any ideas or pointers to how this might be accomplished?
