MOBILE ADCOCK RADIO DIRECTION FINDING ANTENNAS

  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 (click product link for photos and data sheets):

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 (27-88/88-220 MHz; optimum sensitivity in aviation band)
DMA-1271B1 (27-88/88-270 MHz)
DMA-1272B1 (27-88/88-300 MHz)

DMA-1309B1 (75-220 MHz; optimum sensitivity in aviation band)
DMA-1310B1 (75-300 MHz)
DMA-1310B2 (75-300 MHz)
DMA-1315B1 (80-250/250-520 MHz)
DMA-1325B1 (75-1,000 MHz)    
DMA-1349B1 (148-470 MHz)  
DMA-1366B1 (220-520 MHz)
DMA-1418B1 (370-1,000 MHz; optimum sensitivity in cellular/pager band)
DMA-1915B1 (1,550-1,600 MHz GPS interference location DF antenna)

Custom models are also available on special order for other bands in the 20-1,600 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.
