The base is Antenna Specialists ASP-3, the spring ASP-570, and the whip itself is a 96 inch one. Mike C. could confirm the last part. I need to add those to the Resto doc.
It's actually not a CB antenna.
Here's a place that has the bases....you may be able to google the model numbers and find one that's cheaper, though. Good luck.
