I'll give 10 stars for the quality of this kit! HOWEVER, after 4 straight days, (my entire labor day wknd) of messing around with it, I couldn't get the swr readings under 2.5! no matter what I did I couldn't get below 2! and YES, I was using a external swr meter!! I tried absolutely EVERYTHING but no matter what I did I just couldn't get the numbers down! moved it from rear of fender to front and nothing happened! very disappointed in this! I called 2 cb professionals one with 37yrs experience and he said, "those hood channel mount kits rarely work on most vehicles especially ones that are all metal. their mainly used on jeeps or vehicles with minimal metal bodies due to reflection and thats what your experiencing"! I ran tinned copper braided body grounding straps in 6 locations, even the body of my radio is grounded, but no matter what I did nothing helped! while this isnt RCR's fault I do feel slightly mislead! but im not blaming RCR for my bad experience. this was purchased for my 2011 F150. while my experience was horrible, and expensive, I'm not going to say this kit won't work for you! but in my experience it's a HUGE waste of time and money! but the quality of the firestik FS II antenna is great! the mount is very sturdy, spring is very good quality and will handle the 4 foot antenna great! the quick connect is awesome and is perfect for removing so somebody who doesn't want they're antenna stolen off they're vehicle can easily remove it!! again, this is not in any way a negative review of right channel radios!! they just sell the products! I will shelf this kit and maybe it'll work on a different type of vehicle. but in the case of my F150, it just won't work! good luck to anyone who buys this kit, I hope you have better experience with it than I did!! switching to a magnet mount because thats what every pro is telling me!! very happy with RCR and no "bad feelings" towards them👍
