Omnidirectional and Microwave Antennas; ODA-4 | MWA-6 | MWA-12
 
All antennas work well with the Pro 1206i, Pro 1207i and 3-Band 1216 bug detectors and can also be used with any RF device, including RF detectors, spectrum analysers, receivers, and more.
 
ODA-4 OMNIDIRECTIONAL ANTENNA
 
The ODA-4 antenna boosts sensitivity on lower frequencies up to 3 - 4 GHz. You'll see the biggest improvement in the 80 - 700 MHz range.  This boost is especially helpful for spotting or receiving signals on VHF, UHF, ISM 315, and 433 MHz bands.
 
MWA-6 MICROWAVE ANTENNA
 
The MWA-6 antenna increases sensitivity from 800 MHz - 6.0 GHz (covering all mobile and WiFi bands). It's particularly good at finding GSM, CDMA, 3G, 4G (LTE, Wi-Max), WiFi 2.4 GHz, Bluetooth, WiFi 5 GHz, DECT and other digital transmissions.
 
MWA-12 MICROWAVE ANTENNA
 
The MWA-12 antenna boosts sensitivity from 2 - 12 GHz (starting from WiFi 2.4 and up).  You can use it to filter out some mobile bands and focus on WiFi 2.4 and WiFi 5, or to spot signals above 2 GHz: 3G, upper band 4G/LTE, WiFi 2.4 GHz, Bluetooth, WiFi 5 GHz, wireless cameras, and more.
 
Thanks to its directional design, you can quickly pinpoint the signal source.  Plus, it can detect signals from at least twice as far away compared to omnidirectional antennas (with a 6dB gain).
