I would say Bill's description is pretty much spot on.  I've been using one
for years.

It has a very noticeable amount of gain over a dipole or loop.  Yes, you do
have to turn it, but it has a very broad pattern so you don't need to turn
it much.


As a few of the other guys have pointed out, they are a bit fragile.  That
"closed loop" design tends to grab every tree limb it passes.  However, even
if it is a bit bent up and saggy from the abuse, it still performs well.
I'm still using my first one, and when it finally impacts it's final tree
limb, I will buy another!

Many rover stations are using the Par Moxon with good results. It is a 2
element Yagi with the element ends bent toward each other so it "looks like"
a loop. The Moxon has gain over a dipole where a single loop has gain LESS
than a dipole. The Moxon is probably about 6dB better than a single halo. Of
course you have to POINT the Moxon, but unless you're doing a lot of
operation while in motion, that's not usually a problem. In either case
(halo or Moxon), try to get the the antenna as far off the ground as
possible to keep the vertical lobe on the horizon. A 6M antenna at 8 feet
has the main lobe pointing way up off the horizon and very little ON the
horizon, that's why it works so well on E-skip, especially short skip! I run
my 2 element beam at about 16 feet on the rover.. It probably wants more!
