LPA500 UHF Log Periodic Antenna
Owner’s Manual
Description
The
Log periodic antennas are very directional and will have the best reception when pointed at the transmitter. This design also means less interfer- ence from unwanted signals coming from the back or side of the antenna.

1/2 Power Beam Width | 120° |
19.4 dB | |
SWR | 1.5:1 |
Input Impedance | 50 ohm |

Placement
The LPA500 should be placed in a position that has a clear, unobstructed path to the transmitter. Obstructions to the signal such as walls, ceilings and metal objects will reduce range and perfor- mance.
Generally speaking, placing the LPA500 at an elevated location will yield the best performance over the largest area.
Antenna Mounting
The LPA500 is supplied with a variety of mounting hardware to make installation easy. It should always be mounted vertically with the arrow pointing towards the transmitters(s). See Figure 1. when oriented correctly, the LPA500 will appear as a thin piece of metal when viewed from the transmitter’s position.
For best results, do not clamp the LPA500 to horizontal metal objects that extend past the clamp (see Figure 5). Metal rods or other objects that block part of the large face of the antenna will detune it and cause loss of performance.
