 Either the Sonar DF-6F (shown here) or the loop Sonar Model 45 could be considered the "sister" unit to the Sonar Model 45 Radiotelephone, as both appeared in the same ad in 1961. |
 And
alternately, with the loop model 45. The cabinet is the same color as
the radiotelephone, and the speaker grill has the same red plastic
logo, but the face is not dark brown like the ferrite bar DF shown
above.So there is no clear match, really. Perhaps in the case of Sonar, they never really worried too much about making matching electronics. Cabin decor... not high on thier list of priorities! It was, with Bendix, apparantly... shown below. |
 Radiomarine AR-8711 RDF, and ET-8044 Radiotelephone. If you were outfitting the electronics on your 1952 Hatteras motor yacht, or Alden ketch, this would probably have been your radio set of choice. Power, quality, reliability, performance, you could not go wrong. Of course the sets, antenna, power supply and installation probably would have cost over $800, which I think would translate to about $8,000 to $10,000 in today's dollars! But the technology was there, and the only way to get it was to pay for it... if you could. |
 Bendix Skipper Custom Skipper 28 radiotelephone, with sister Bendix Navigator 440 radio direction finder. |
 These two also clearly go together: The Ray-Jefferson model 483 RDF, and model 635 Radiotelephone. I know the radiotelephone is from about 1959, so I would assume the RDF is about the same vintage. I repainted the radiotelephone, as the front panel was badly rusted. And while I was able to mateh the main cabinet hammertone pretty closely, I could not find a close match for the slightly lighter front panel. But originally, the front had the same color as the RDF. |
