[ARC5] U.S. WW II equipment

[Sandy Blaize]

We had them on the F-86D and F-86L birds.  Seems like there was one on our 
T6.  I don't remember what our C-45 twin Beech used.  The T-33's used them 
of course.  We only had a couple of T-birds by then.  The old C-47 used the 
SCR-269G or the ARN7.  I remembered the sense antenna "field" that was glued 
to the interior of the canopys.

Most jet aircraft used the ARN-6.  One reason was that the football antenna 
on the ARN-7 and SCR-269 was not stressed to withstand high speed flight.

The little black part of the nose on the F-80, T-33, F-86, F9F, and many 
other early jets is the radome for the ARN-6 loop.  Other aircraft carried 
the ARN-6 loop underneath the canopy; I suspect the F-86D was one because of 
the radar in its big nose section.  I think the F-100 carried the ARN-6 
under the canopy as well.  Of course many other a/c carried the ARN-6, 
including the C-119, C-123, early C-130, C-131 (Convair 440) and some C-47 
or more probably Navy R4D-8 "Super DC-3" types.

The giveaway for an ARN-6 system on larger a/c is a long, fairly low (maybe 
8 inches) black faired radome about 18 inches long if I remember right; or 
in a jet -- maybe even in some F-51s and F-82s -- a little glass dome 
underneath the canopy behind the pilot's seat.  And the sense antenna is 
built into the canopy on such a/c.
