This is a CX-210 Diamond Antenna, A Heavy Duty Coaxial Antenna Wideband 2 Way Coaxial Switch with SO-239 Connectors. This is from a storage unit so I don’t know much about them other than visual. Wording is what I found from matching items in other listings. Review pics to see what you are getting.
Condition: I assume it is functional but it is untested. Has some slight cosmetic edge wearing to it.
Any questions, please ask.
