Review: Cb - It works great mine is 10ft off my apt ralling I get over 15 plus miles away and swr is 1.5 all channels
Review: No ground plane is what I needed. This is ... - No ground plane is what I needed. This is a 1/4 wave antenna and is very wide banded. It’s low profile, and does not attract a lot of attention. Keep in mind, this is a 1/4 wavelength antenna so the radiation pattern will be high compared to a narrow-banded base station antenna. Wide band=low gain. Please do your research before you purchase.

No ground plane is what I needed. This is a 1/4 wave antenna and is very wide banded. It’s low profile, and does not attract a lot of attention. Keep in mind, this is a 1/4 wavelength antenna so the radiation pattern will be high compared to a narrow-banded base station antenna. Wide band=low gain.
