ODA-4 omnidirectional antenna for RF detectors, spectrum analyzers, and receivers.

The ODA-4 antenna is a great addition to any RF device, including RF detectors, spectrum analyzers, receivers, etc. The usually supplied antennas receive higher frequencies very well, however, they might be weak at lower bands.

This antenna will improve the detecting and sensitivity range of the entire range of 80-4000 MHz, however, the most significant increase in performance will be within 80-700 MHz.

This range is of importance when detecting or receiving the following signals:

VHF, UHF, and ISM 315 & 433 MHz bands. 

Compared to the standard rod antenna of Protect 1207i or iProtect 1216, the ODA-4 gives an average gain of +5...+10 dB in the frequency range 100 MHz - 3000 MHz. 

 

The device is meant for indoor use only, and pairs perfectly with iProtect 1216, particularly on the Band 1 (<700 MHz).

It is also compatible with the 1203 and 1206i.

Can the ODA-4 antenna be used outdoors?
The ODA-4 antenna is designed for indoor use only. Its construction and materials are optimized for indoor environments to ensure the best performance and longevity of the device when used as intended.


Can the ODA-4 antenna be used with any spectrum analyzer?
While the ODA-4 is specifically mentioned to be compatible with iProtect 1216, 1203, and 1206i, its broad frequency range may allow it to be used with other spectrum analyzers that operate within its supported frequencies. However, compatibility should be verified with the specific device manufacturer.


Does the ODA-4 antenna require any specific setup or installation?
While specific setup or installation instructions are provided in the detailed manual, the ODA-4 is designed for easy integration with compatible RF devices. Its omnidirectional design means it does not require precise alignment, making setup straightforward.


How does the ODA-4 antenna improve the performance of RF detectors and analyzers?
By extending the detecting and sensitivity range of RF devices across 80-4000 MHz, with a notable increase in performance within 80-700 MHz, the ODA-4 enhances the ability to detect and receive a wider range of signals. This improvement is particularly significant for signals in the VHF, UHF, and ISM 315 & 433 MHz bands, making it a valuable tool for comprehensive signal analysis.


Is the ODA-4 antenna compatible with devices other than the iProtect 1216?
Yes, the ODA-4 antenna is also compatible with the iProtect 1203 and 1206i RF detectors. This compatibility extends its utility to a broader range of devices, making it a versatile addition to your RF detection and analysis toolkit.


What are the physical dimensions of the ODA-4 antenna?
The provided product description does not specify the physical dimensions of the ODA-4 antenna. For detailed physical specifications, including size and weight, potential users should refer to the detailed specifications manual or contact the manufacturer directly.


What frequencies does the ODA-4 omnidirectional antenna support?
The ODA-4 supports a wide frequency range of 80-4000 MHz, with a significant performance increase in the 80-700 MHz range. This makes it ideal for detecting or receiving signals in the VHF, UHF, and ISM 315 & 433 MHz bands. Its design is optimized to enhance the detecting and sensitivity range across these frequencies.


What makes the ODA-4 antenna a good addition to RF detection and analysis equipment?
The ODA-4 antenna’s ability to significantly improve the detecting and sensitivity range of RF devices, especially in the crucial 80-700 MHz range, makes it an invaluable addition. It enhances the detection of VHF, UHF, and ISM band signals, broadening the scope of analysis and detection capabilities.
