[Antennas] 2 meter antenna

Tue, 23 Jul 2002 08:48:18 -0700

I have to say that Chad's flippant response is not very informative.

As others have pointed out your gain will be up not horizontal.  I will add
to the list of ideas for getting gain towards to horizon:  Every have
wavelength bend the wire into a 1/4 wave phasing stub (make sure they don't
touch!).  This is the old stacked J-pole or super-J.  The more phasing stubs
the more gain towards the horizon, with a law of diminishing returns.

| 1/2
|
-- 1/4 
|
|
--+
|
|
... etc.
