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, it 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 of performance will be within 80-700 MHz.
This range if of importance when detecting or receiving the following signals:
VHF, UHF, and ISM 315 & 433 MHz bands.
