RDF Products offers a wide variety of mobile Adcock radio direction finding antennas covering various bands in the 20-1600 MHz range.  These weather-sealed units are rugged, compact, light-weight, and specifically designed for demanding mobile radio direction finding missions.  They can be mounted on cars, vans, aircraft, or any platform with a sizeable metallic ground plane.  Both single- and multi-band configurations are available. Standard models are listed below along with their corresponding frequency ranges: 

DMA-1248B1 (20-174 MHz; enhanced low-VHF performance) 
DMA-1254B1 (20-470 MHz; S/A DMA-1248 but with added UHF coverage) 
DMA-1265B1 (20-1,000 MHz; ultra-wide coverage V/UHF DF antenna) 
DMA-1270B1 (27-220 MHz; optimum sensitivity in aviation band)
DMA-1272B2 (27-300 MHz)
DMA-1276B2 (27-520 MHz)
DMA-1286B2 (30-1,000 MHz; low-profile, covert)
DMA-1290B1 (65-200 MHz; ultra-wide coverage V/UHF DF antenna)
DMA-1306B1 (65-1,000 MHz; ultra-wide coverage V/UHF DF antenna)
DMA-1309B1 (70-280 MHz; optimum sensitivity in aviation band)
DMA-1310B2 (75-300 MHz)
DMA-1315B2 (75-520 MHz)
DMA-1325B3 (75-1,000 MHz; low-profile, covert)    
DMA-1349B1 (148-470 MHz)  
DMA-1366B1 (220-520 MHz)
DMA-1376B1 (240-1,000 MHz; optimum sensitivity in 700-1,000 MHz cellular/pager/trunking bands)

Custom models are also available on special order for other bands in the 1.8-1,000 MHz range.

RDF Products can also supply special-purpose DF antennas for customers who wish to employ proprietary signal processing hardware and bearing computation algorithms rather than using an RDF Products DF receiver/processor.  Such antennas can be supplied with standard Adcock-style outputs or with direct phase-matched aerial outputs more suitable for interferometric DF applications.  We invite customers with such special requirements to contact us for further information.
