[MRCA] Antenna Nomenclature Query

[D. Platt]

Gentlemen,

I'm getting ready to list an antenna assembly and I'd like to know the 
correct nomenclature.  Similar to the GRA-4 and the RC-292, it has 8 ea. 
6' aluminum (O.D.) mast sections, canvas/wire rope mast storage assy., a 
dipole coax center insulator, 1 set of guy ropes and ring, mast base, 
two dipole reels with wire, and stakes.  I have two but will retain one 
of them... just in case....!  We used these antennas in CAP for HF for 
years, using a multi-band dipole set up an an inverted-V.  The dipole 
center insulator says: L4/GRA-4 but the GRA-4 book says the mast 
sections are but 3'?  Again, anybody know what these actually are?
