I built my shunt feed wire cage based on the design in Jeff Bigg's K1ZM
book "DXing on the Edge..." I bought it from the ARRL bookstore but you might
be able to find it on Amazon, etc. I used two widely-spaced wires whereas he
used three in a triangular form held off the side of
Gene,
The cage design sounds very interesting. I just ordered the book :-)

It is important to realize that a cage just hung of the side of a steel
tower has some drawbacks. The pattern when modeled is somewhat
asymmetrical to a slight degree. In a properly designed cage feed it is
the cage that does the radiating and not the tower. (Above the cage is
mainly the
Stan,
With shunt feed I would gain the 18 foot mast with the yagis, the total
overall height is 108 feet.
I haven't really considered shunt feeding. I see your point of the
wires with an L in proximity to other
antennas. That was a worry I had with the 40 meter yagi and the L. I
will look
If you have such a structure IMHO the best thing you can do is to shunt
feed it. It is really easy to do. Just drop a three or four wire
"cage" down from the 60 foot level supported by two pieces of galvanized
water pipe extending each about 24-36 inches from the tower. . and
feed the
Gentlemen,
Thanks for all the info and advice on putting up a 160M antenna.
I have received help both on and off the reflector.
I wasn't sure whether to post the question because I know you have
discussed
this many times before !
thanks, much appreciated !

I am planning an install of a 160M inverted L and would like critique
from you top banders.
I was originally planning a separate tower for 160 but my XYL has
squashed the idea :-)
My tower is 90 feet fully extended with a 18 foot mast currently used
for a Force 12 WARC plus 10/15 beam
on top
