Connecting and Positioning of remote Antennae
In multichannel systems
we recommend the use of the GPA 700 groundplane antennae
in conjunction with the ZAF 500 N antenna connection panel and low attenuation antenna
cables such as AVK N(HF)-N(HF) (LA). For mounting the antenna use the AMK 700 mounting
device (on top 3/8" external thread for connection to GPA 700; on bottom 3/8" internal thread
for stand mounting). You can mount the antenna cable to the stand with the ZKV 700 clamp for
strain relief.
1. Connect the GPA 700 receiving antennae to the corresponding antenna inputs and place
the antennae to the right and left of the receiver. Diversity reception is improved when the
antennae are vertical or slightly tilted.
2. The distance between the two receiving antennae should be at least 1 m.
3. The distance between transmitting and receiving antennae should be at least 3 m to avoid
overloading and interference between different channels. We therefore recommend
installing the antennae in a high position, especially in multi-channel systems.
