Impact of Antenna Choice
The antenna directly affects signal distance, connection
quality, and interference levels.
Wireless Wiegand comes with a built-in status display and diagnostics, enabling installers to fine‑tune link performance effectively on-site:
Signal strength percentage shows signal link quality.
A packet loss graph (60 sec, 10 min, 24 h intervals) helps detect intermittent connectivity.
Event loss and code logs display actual card reads, including UID codes and Wiegand port info, confirming true system operation.
Omnidirectional antennas provide 360-degree coverage and are ideal for installations where signals need to be transmitted in all directions equally.
Description: A flexible, vertical antenna commonly used in
access control and wireless communication systems.
Pros: Easy to install, provides uniform radiation in all directions.
Cons: Limited range compared to directional antennas.
Example Applications: Reader-to-controller wireless communication in small
office or residential installations.
Description: A two-element antenna with improved efficiency
over whip antennas.
Pros: Better performance and range compared to single-element antennas.
Cons: Requires specific mounting orientation for optimal performance.
Example Applications: General-purpose access control setups.
Description: A flat, rectangular antenna that directs
signals forward.
Pros: Higher gain than omnidirectional antennas; reduces interference from
other directions.
Cons: Limited to fixed mounting positions.
Example Applications: Entry points where signals need to be directed towards
specific areas.
Description: A multi-element antenna designed for high-gain,
directional applications.
Pros: Excellent range and efficiency for point-to-point wireless links.
Cons: Requires precise alignment and mounting.
Example Applications: Long-distance communication between remote access control
points.
Description: A high-gain dish antenna that focuses signals
in an extremely narrow beam.
Pros: Maximum range and minimal interference.
Cons: Bulky and requires precise alignment.
Example Applications: Large industrial or campus-wide access control networks.
1. Frequency Compatibility – Ensure the antenna supports the 800/900 MHz ISM band.
2. Coverage Needs – Choose omnidirectional for broad coverage, semi-directional
for focused areas, and directional for long-range links.
3. Installation Environment – Consider obstructions, interference, and mounting
options.
4. Antenna Gain – Higher gain improves range but reduces coverage angle.
Make the most of your antenna setup with these quick field-proven tips:
✅ Match Antenna Polarization
Ensure both antennas are mounted vertically (or horizontally). Mismatched polarization can reduce signal by 20–40 dB.
✅ Fine-Tune with Built-In Tools
Use the WW device screen or web interface to monitor:
Signal strength (%)
Packet loss trends (live graph)
Real-time card reads and Wiegand data
✅ Avoid Reflective Obstructions
Stay clear of metal scaffolding, rebar, power boxes, or heavy RF noise sources nearby.
✅ Mount Securely
Use rigid mounts—wind, vibration, or loose brackets can cause misalignment or dropouts over time.
✅ Adjust in Small Steps
During setup, move antennas in small increments while watching signal feedback. You don’t need third-party analyzers—WW shows you everything you need.

Custom Cables for Optimal Performance
Using the right cable length is essential to minimize signal loss and interference in Wireless Wiegand and 900 MHz ISM band applications. Pre-cut cables can introduce excess length, causing unnecessary attenuation.
For best performance, it’s recommended to custom-build cables to exact lengths needed for your installation. This reduces unnecessary signal loss and improves system efficiency.
