Ed:
40 years ago I bought my second beam a Mosley TA 33. Above 20M the across the 
pond (E US)
Dx would chase it. Rare DX would usually answer. 

I was also leery of the traps. No problem over many years. What you have to 
concern yourself
about is aluminum oxidizing Approx. every 2 years you have to deoxidize 
particularly the connections.
You Google for compounds cleaning or Mosley sells it had has a maintainability 
article on it.
 I wish I saw it years ago.

Here are on the east coast Asia is the challenge so I recently put a new TA 33. 
Outstanding results even during contests.
I use a dipole to listen because the beam significantly diminishes off center 
signals. That's how we get the gain. 

I suspect The reason of different opinions lies in Mosley performance in non 
10-20m bands.
I hear Mosley is not so good in these bands. I don't work there so I don't know.
This QTH is at the bottom of a hill and the Oaks grow 100+ feet to catch the 
sun.
Carving out beam rotating space is a chore to start and maintain. So I am very 
happy with
the TA 33 small 15.5 foot turning radius. The traps allow the smaller turning 
radius. For results to cost and size ratio the 
TA-33 in 10, 15 20 is a winner. The other bands I know not.

40 meters is the band for most frequent Dx. If you are interested I'll send you 
specs
for a Windom that gets great 40M results. The even high harmonics are also 
good. Some claim 
the "new" bands work with this ant and a tuner. I can't say.

Here are a few TA 33 / beam interesting web sites 
http://www.kt4qw.com/ta331.htm turns a ta33 into 17M.
Google ta-33 antenna for articles and a great set of images. This branches in 
to many antenna types.
