[TowerTalk] 10 throu 20 beam traps or no traps

[Jeff AC0C]

If I recall, the Mosley beams faired quite poorly in the K7LXC/N0AX test. 
These beams do have a reputation for being well made, however.

The best performing were the Force12.  The Optibeam and the Force12 are of a 
similar design concept.

For that reason, of these two choices, the Optibeam would seem the better 
choice.

I've not seen these antennas, but the designs look first rate.

>From the looks of it, the 9-5 is two elements per band, equivalent to
the 2-element SteppIR. The 11-5 appears to be three elements per band,
equivalent to the 3-element SteppIR, and the 16-5 looks to be four per
band, equivalent to a 4-el SteppIR.

I'm very happy with my 3-el SteppIR, and use it all the way up to 6M.
Two really good features -- the straight SteppIRs weigh a lot less, so
are easier to handle on the tower and don't need as big a rotor. Second,
the reversing and bi-directional features are worth it's weight in gold.
Except on 6M, where it doesn't work that way, I rarely turn the antenna
more than about 100 degrees.

Here in CA, South America and Asia are approximately opposite of each
other, and the higher bands are often open to both at the same time.
Reverse takes something like 3-5 seconds. Likewise, EU and the east
coast of the US are opposite to VK/ZL. Very useful in a contest.
