I have a very new BCD436HP handheld and I recently purchased a UHF SMA rubber antenna that extends below the SMA tip. When I screwed the antenna down into the gap around the plug, it pushed so tightly against the nut that unscrewing the antenna also unscrewed the nut around the antenna socket. I was able to tighten it again with a small screwdriver, but I was wondering if there is some kind of tool that the repair techs use for these antenna nuts. I did a brief google search and it sounds like the tool may be called an antenna spanner nut tool or something. Thanks for any help on this.
