INSTRUCTION MANUAL

General Description

The ALP-450 is a broadband directional log peri-

odic antenna. It will receive any frequency from

450 to 900 MHz. The “gain” of this antenna en-

ables it to receive signals from a greater distance

than a typical “whip” type antenna.

Antenna Placement

The ALP-450 should be placed in a position that

has a clear view of the transmitter(s) for best re-

sults. Obstructions such as walls, ceilings, and

metal objects will reduce range and performance.

Antenna Mounting

The ALP-450 is supplied with a variety of mount-

ing hardware. It should always be mounted verti-

cally with the arrows pointing toward the

transmitter(s). See Figure 1.

Log Periodic Antennas are also directional (like a

TV antenna) and will have the best reception when

pointed at the transmitter. This yields the benefit of

less interference from unwanted signals coming

from the back or side of the antenna.
