Right on the money... the 420 end mounted at the top of a tower has enough end torque to actually flex a Rohn 55 section (in a >35mph) quite a bit. Enough to make me really nervous.
You can "in-line" the dipoles of a DB-408 per Decibels information to obtain a sort of colinear pattern, which is bi-directional to an extent. Side mounted, the 420 kicks fanny (a nice way of saying butt), but you really don't want that much antenna at the top of a tall skinny tower. The DB-411 is a pretty nice 4 dipole unit, it will give you a nice directional lobe in the desired direction. It's also a good preformance/gain vs length antenna. cheers, skipp > "Chuck Kelsey" <[EMAIL PROTECTED]> wrote: > I think my wife stole my Decibel catalog ;-) > > The 413 is 8 elements and the 411 is 4, right? > > If you're going to side mount on a tower, use either. > If you're going to top mount, I prefer the shorter 411. > The longer antennas have too much flex in > the wind to top mount, in my opinion.
