I ordered a CB (27 Mhz) antenna not a 26-30 Mhz adjustable antenna. I tried to adjust the antenna (cut/extend)but the SWR was so bad on ch 1 & Ch 40 I could tell based on the provided instructions what to do, cut or extend. I purchased a Radio Shack antenna instead and the steel antenna was easy to adjust. I liked the reviews on the Wilson 'Little Wil' and how the antenna looked but it should have been close to the frequency or at least adjustable without cutting steel. The instructions says "the whip is generally longer than necessary for ch 1-40" and "if you have an SWR meter". You will NEED an SWR meter (I have one)and something to cut steel in 1/4 sections until you get it right. I use to cut steel whips in the old days when they were over 100 inches in length but a loaded whip? This antenna was so bad I could hardly receive any local traffic on nearby I95 let along transmit. Maybe I got a bad antenna.
