Gen eral De scrip tion
The ALP-600 is a broad band bi-directional log pe -
ri odic an tenna. It will re ceive any fre quency from
520 to 760 MHz. The “gain” of this an tenna en ables
it to re ceive sig nals from a greater dis tance than a
typ i cal “whip” type an tenna.
An tenna Place ment
The ALP-600 should be placed in a po si tion that
has a clear view of the trans mit ter(s) for best re -
sults. Ob struc tions such as walls, ceil ings, and
metal ob jects will re duce range and per for mance.
An tenna Mount ing
The ALP-600 is sup plied with hard ware for tu bu lar
clamp ing. It should al ways be mounted ver ti cally
with the ground and per pen dic u lar to the trans mit -
ter(s), See Fig ure 1.
Log Pe ri odic An tennas are also di rec tional and
will have the best re cep tion when pointed at the
trans mit ter. This yields the ben e fit of less in ter fer -
ence from un wanted sig nals com ing from the back
or side of the an tenna.
