Review: These antennas seem to hold up well, and work good too... - Review Date/ Revision: 1-29-2017/ A. Excellent CB and 10m antenna... Has wide bandwidth - will cover CB to 10m if tuned (cut*#). Use of a short spring is suggested. Make sure spring used, has the braid inside the spring@, or the SWR will be a problem (as you drive down the road - Parked it might be OK)... It probably could be used without spring, if what ever it contacts is in the upper 2/3 - 3/4 of the antenna... ------------------------------------------------------- Notes: * The antenna is likely to cover 26.8-28.3 MHz as is... @ Its become common for companies to leave out the required braid inside the spring. This causes the SWR to vary extremely, as the spring bends. # Cutting and tuning: CB, no spring... -- Use a hack saw. DO NOT use wire cutters on the outside. Cut around the circumference of the tip of the antenna. -- Dont cut more that 1/4 inch, at a time. -- Replace red cap during EACH SWR testing. With a short spring, expect to cut 1/2 inch off. Once you done, Use RTV silicone to glue the cap on permanently. HAM, no spring... -- Use a hack saw. DO NOT use wire cutters on the outside. Cut around the circumference of the antenna. -- Cut 1 inch off (about 1in per MHz) to get to 28.5 MHz, -- Dont cut more that 1/4 inch, at a time, after you get to 28.0 MHz. -- Replace red cap during EACH SWR testing. With a short spring, expect to cut 2 inch off. Once you done, Use RTV silicone to glue the cap on permanently. In my application, I used a Hustler ball mount and spring. This adds to the antennas length. I found it resonated around 26.0 MHz. I cut 2.5in off to get to 28.5 MHz. The bad news is the resonated SWR was around 1.6 SWR, as in it was not a flat 1.1 SWR.
Review: Pre Tuned.........For REAL !!!! - Been using Francis for 36yrs. A slip seat Trucker, in and out of many trucks.. if you can"t get a good SWR Do not think its the antenna ! look eleswhere....Mount...Co-ax...ect.. these are awesome, well tuned from the factory..Many drivers have been using these.. for many years..I run a STRYKER CB..penty of power with No problem...
