UHF WIDEBAND LPDA ANTENNAS, 440-900 MHz

Audio-Technica ATW-A49 UHF wideband LPDA (Log Periodic Dipole

Array) antennas provide enhanced signal pickup for UHF wireless systems

operating over 440-900 MHz, a remarkable 2-to-1 frequency range. This

bandwidth includes all UHF TV channels. Supplied in pairs, these directional

antennas are ideal for extending the operating range and reliability of

diversity UHF wireless systems. They also eliminate the need for multiple

frequency-specic antennas.

The ATW-A49 is designed for applications requiring increased distance

between the transmitter and the receiver - as in stadiums, concert tour

venues, theater and large performance areas, or any area where line-of-

sight may be obstructed. This ruggedly constructed paddle-style antenna is

equally suited for installed and portable applications.

The antennas are compatible with virtually all UHF wireless receivers

and provide a directional coverage pattern with a typical beamwidth of

90 degrees. They offer approximately 6 dB of RF gain improvement over

standard receiver whip antennas. Antenna impedance is 50 ohms.

The antennas are constructed of industrial-grade copper-clad epoxy

berglass. This heavy-duty, durable construction is engineered to resist the

effects of corrosion, UV degradation and vibration, providing long life and

stable performance under difcult operating conditions. High-quality, low-loss

BNC connectors are positioned to minimize RF cable strain. The antennas

are supplied completely assembled.

Location

For best performance, the antennas should be mounted:

- Above head-height,

- In direct line-of-sight to the likely transmitter location(s).

- At least 1m away from eash other, and

- At least 1m away from any large metal objects or sources of interference.

In addition, the length of RF cable run to the receiver should be minimized.

Some experimentation with antenna positioning may be r equired to

determine the best locations under typical conditions.

Important: While the antennas themselves are weather resistant, outdoor

use should be temporary only and under dry conditions. Any moisture or

corrosion in BNC cable connectors or associated cables can greatly affect

RF performance at these frequencies.

ATW-B80 UHF in-line +3dB / +10dB ampliers.

Mounting

The ATW-A49 mounts to a ⅝”-27 thread tting. The antenna mount is designed

to allow for vertical tilt adjustment through a 90° range. Horizontal adjustment

is accomplished by rotating the antenna in the mounting fitting. For portable

applications, the antenna may be installed on a standard ⅝”-27 t hread

microphone stand.

Connections

After the antennas have been installed, connect them to the antenna inputs of

either a wireless receiver or an antenna distribution system. Use RG58-type

cable for cable lengths of up to 7.5m. For cable lengths greater than 7.5m, RG8-

type low-loss RF cable is recommended. RG8-type cable lengths over 50m may

cause significant signal loss. Because cable requirements vary considerably

from one installation to another, RF cable are not included. High-quality, pre-

terminated RF cables available from Audio-Technica will be found listed on the

“Optional Accessories.”

UHF宽带对数周期偶极阵(LPDA)天线, 440-900 MHz

ATW-A49 LPDA( -Log Periodic Dipole Array)宽带对数周期偶极阵

天线，为频段的无线系统提供合式的高增益UHF 440-900MHz 2 1

的接收能力，而接收频带已覆盖整个电视通道。对装式的定UHF

向天线设计，为分集式无线系统提供理想的远距离和稳定的UHF

接收表现。另外，亦可作多通道无线系统的共用天线。

ATW-A49是设计于需要远距离接收和发射的应用，如体育场馆、

演唱会、剧场、及大型演出场所；或一些会阻挡视线及接收的环

境。另外，天线可轻易稳固的安装；同时亦可容易地拆除，方便

携带。

该天线差不多可使用于所有频段的无线接收机中，并提供UHF 90°

角度固定频带中的定向覆盖接收。比较接收机附带的标准天线，

ATW-A49可提供在50欧姆阻抗时约6dB的射频信号提升。

ATW-A49天线是以工业级标准的玻离钢及铜膜镀层构造，提供耐

用、防腐蚀、抗紫外线、防震及轻型的特点，在不同环境下可作

长时间及稳定的表现。而线整合的端子提供了高质量及低抗BNC

阻抗的特性，并能减低连接线的拉力。

安装位置

为提供最好的表现，天线应安装于：

- 高于一般人头顶高度。

- 可直接看到发射机而无障碍物的位置。

- 旁边的物件应与天线有最小1米的距离。

- 与大型金属品或有干扰的信号源，应有最小1米的距离。

另外，连接到接收机的同轴电缆应尽量减短；而在许可情况下，

可尝试把天线放置在不同位置以测试出最好的接收效果。

注意：天线会受到天气环境的影响，在户外使用时，请把天气放

置在干固的位置，湿气及雨水会影响端子及电缆的表现及安BNC

全。
