BULLETIN # 11
MODEL: TR-2200A
SUBJECT: ADAPTING THE TR-2200A ANTENNA TO OTHER RADIOS

                                                        
      We have had several inquiries about adapting the TR-2200A whip
      antenna to the Drake TR-22C and Trio TR-2200. We now have a
      kit of parts to do this. Following is a copy of the instruction
      sheet supplied with each kit.
      
                  TR-2200 Antenna Kit Instructions

                 7   Pipe                  F29-0018-14     1
                 8   Ground Lug            E23-0015-04     3
                 9   Screw                 3x6 mm          1
                10   Cable with capacitor                  1
      
         1 - Remove original antenna

         2 - Enlarge antenna hole to 9.5 mm

         3 - Install parts 1 thru 8 as shown in the graphic

         4 - Remove coaxial cable that runs from the original whip
             antenna to the S0-239.
    
         5 - Connect original coaxial cable from terminals ANT and E
             to the external antenna connector (S0-239). (This cable
             originally went from terminals ANT and E to the whip
             antenna.)
    
         6 - Locate the 2 "L" brackets mounting the TX unit to the
             side and install 2 ground lugs between the bracket and
             the side ot the unit.
    
         7 - Install the coaxial cable so that the end with the
             capacitor is at the S0-239.
    
         8 - Solder the free end of the capacitor to the center pin
             of the S0-239 and solder the coax braid to the ground
             terminal.
    
         9 - Mount the last ground lug wlth jXb mm screw at the hole
             next to the whip antenna.
        10 - Solder the braid of the supplied coax to the ground lug
             installed in Step 9 and the center conductor of the coax
             to the antenna lug 2.

        11 - Carefully solder the coax braid to the 2 lugs installed
             in Step 6. See graphic
