I need the inside part of the antenna jack that is behind the front panel or the complete jack. Is there a part number or source? The replacement fuse did not go into the center of connector and crushed the contact.

finding new may be tough. closest is a JFW BNC inline fuse. Pasternack used to have one @ 75.00 each.

best bet is to either
1. repair the damaged connector
2. salvage one from a scrap Motorola service monitor ...used on the R20XX, R22XX , R24XX and R26XX series.
3. Bypass and just use a jumper soldered to the damaged center pin. You could try and place a fuse further back in the RX assembly

Good luck ...maybe someone else has a better idea.

Fieldcomponents.com might have a connector or be able to make one. Is the connector inside R2400 a sma male or female?

these are the fused front panel BNC connectors. A portion of the BNC unscrews and a 1/16 amp pico fuse is inside.
newer designs avoid using these fuses and have a more sophisticated approach to over power situations on RF ports.

R2400 was shutting down every 10-15 minutes. I jumped the thermal breaker and it run for an hour before I turned it off.
