Write your reply.

assistant: The old monopole has been around since the fifties, a darn reliable 50
ohm antenna that can take direct lightning strikes, won't detune when
coated with three inches of ice and can cover a wide frequency range
without realignment.  The downside is no gain (but also no loss) over a
1/2 wave dipole.  Also the radiation pattern is very simple and
predictable.  Great for repeaters!

vertical - flat VSWR across the 40m band.  For 80m we used an inverted Vee

assistant: Ralph & Clay-
     I put up many dipoles in my younger days.  My experience was:
  1.  Cut per the formula (derived from 0.95 times freespace length).
  2.  Put it up ANY way it would fit, hopefully with more than 90 degrees
angle!
  3.  It would work well.
     I considered an SWR of 3:1 or better, to be a "success", since the
old transmitter's PI-network could easily match it.
     In today's world, it isn't quite that easy.  Modern solid-state
equipment has a fixed-tuned output stage, consisting of a filter designed
to work into a 50 Ohm load.  Therefore, you must provide either an antenna
with SWR better than 2:1, or use a matching device/antenna coupler of some
kind.  In other words, the problem isn't really with the antenna, but in
the rig's ability to deliver full power to a load that isn't close to 50
Ohms.
     Can you tune a dipole, so it will have low SWR across the entire
band?  Maybe so, at Thirty Meters and above.  Maybe not, at Forty Meters
and below.  If you work a lot of Seventy Five and Eighty Meters, an
antenna tuner may be required.  Even so, the range of the built-in
auto-tuners should be adequate for a full-size dipole tuned for the center
of the band.

assistant: Tom-
     I think YOU are the one fighting this!  Obviously, the information
contained in a digital transmission was encoded.  (Ever hear of Morse
code?)
     Is it really illegal to receive and decode TV from the satellites?  I
doubt it.  It isn't as if you strung a co-ax out the Cable company's
lines, and tapped them.  The airwaves are free, at least to a point.
     Historically in the U.S., there has been a "secrecy of
communications" law, where you can receive anything within your
capability, but you can't divulge it to the public.  In the case of TV,
you would definitely put yourself at odds with the law, if you received
the signals and re-distributed them to your neighborhood.
     Do you believe the law applies if you watch them in the privacy of
your home?  Or, do you merely have a financial stake in having us believe
in the illegality?!

The antenna was on a ranger station at a campground.  Looked to be just
a tad short for 2M but my memory's not what it used to be, it definately
wasn't short enough to be in the 220 MHZ range.
Can you elaborate a little on how the higher impedance improves the
radiation efficiency.  I am trying to learn more about antennas and the
sources of in depth explanations are few and far between.

 I'm using a trapped dipole on 160 and 80m now and the idea of a folded
antenna intrigues me.
 If the folded dipole antenna were a full wave-length antenna (folded) would
it work the same as a folded 1/2 or 1/4 wave-length antenna or better?
 Was curious if the folded full wave for a band could be built and how it
would
stack up against a folded 1/4 or 1/2 wave on that band.

 Afterall, the transverter is in essence converting the 2 meter rig
 to a 6 meter rig.   Therefore the Ten-Tac 6 meter would work as well
 on one antenna as another.  Since the AR-6 is a six meter vertical
 antenna it stands to reason it should work quite well on FM.
