[MRCA] IN-106A antenna base for the SCR-284 - What the heck?

[Dennis DuVall]

Garret,

The two bottom sectors  of the SCR-284 “rod” antenna, MS-56 and MS-55 are unique to the SCR-284.  The bottom section, MS-56 has a smooth cylindrical bottom end that fits into the 1N-106A.  The top end of MS-56 mates with the bottom end of
 MS-55, the top end of which mates with “standard” section MS-54 and so on up through MS-55, MS-54,  MS-53, MS-52………….MS-49 (top section).

MS-56 (bottom) sections are now extremely rare, the last one I saw on eBay went for $500!  Better start thinking about some kind of adapter.  Got a machinist friend?
