[Drake] R4B antenna connector

[Garey Barrell]

John -

No, I don't believe any Drake 4-Line gear ever came with BNC 
connectors.  However, I have seen quite a few with a BNC for the ANT 
connector that was added 'aftermarket'.  Amphenol offered a BNC 
connector designed for single-hole mounting that would fit into the hole 
provided for the RCA Phono jacks that Drake used.  Seems like it was 
3/8" dia and came with a lockwasher and nut.  The ANT jack was often 
damaged by those who insisted on attaching a piece of RG-8 with three 
adapters right at the connector, which of course cracked the ceramic 
insulator in the jack.

The SPARE 'hole' was on all the "B" models, not sure if there was ever 
an intended use.   The CC-1 VHF accessory requires two added connectors 
on the T-4XB, and holes were also provided for them, but I don't think 
there was any need in the R-4B.  I guess it could have been used as an 
IF output for a scope, etc.
