Classic CB Base Station Antennas

June 6, 2019

The best CB base antennas were manufactured in the 1970s and early 80s. Reason? They were made out of metal. In the early 1980s (1984, I believe), the Consumer Products Safety Commission began requiring that omnidirectional antennas meet certain standards. This was due to the large number of people who had been electrocuted while installing… Read More »

My friend Kathy found this and sent it to me on Facebook.

Back in the pre-40 channel days, Dynascan’s Cobra 29 was quite possibly the best AM mobile CB radio you could buy. This radio was extremely well made. Audio was very strong, courtesy of Cobra’s exclusive DynaMike. The Cobra 29 was a very nice looking radio with plenty of knobs, bells & whistles. Power/volume, DynaMike, squelch,… Read More »

This is the Dynascan Cobra CAM 89 base station. It looks like a Cobra 139, but doesn’t have SSB (single sideband.) Basically, it’s a Cobra 29 with the addition of a built-in power supply.

This Cobra 138 is the upscale cousin of Dynascan’s most excellent Cobra 29. These two CB radios are very similar with one important difference: the 138 adds upper and lower sideband capabilities. Appearance and performance are both excellent. This was one of the “Classic Cobras” that made this brand so successful back in the 1970s.
