    that's why I like the 102"whip. I see it this way, its a solid piece of metal, tuned to the appropriate wavelength, what you see is what you got. no hidden caps coils or other components used to match the load. its kinda like the antenna tuners you see, that resister was probably added to make up for the missing 18" of metal on the 7ft whip. the problem is that it will lower the swr on a meter but its really not lowering the swrs just the needle of the meter, which you can do with resisters all the way down to a dummy load which will give you a perfect match on the meter even though you no that aint getting out. so be careful with your perfect 7 footer someone has added something to make it appear perfect(resister)

    102" whip is the best all steel cut to wavelength. no hidden caps resistors or coils to make the antenna match its load. what you see is what you get. your 7 footer has a resister added to make the radio appear to be a perfect match. its just like a junkie antenna tuner. it doesn't tune the antenna, it just lowers your swr reading to make you happy its still performing like a mismatch antenna I promise you remember you can pile up resistors till the point you've made a dummy load. they match great on the meter but they don't get out

    folks get so caught up with the length of the radiator they forget that it is only half of the antenna , the other half is the ground element .... which may be wires or tubes or the metal in the body/frame of a vehicle . adjusting the length , size shape/angle or centering of that/those ground element(s) will adjust the tuning/vswr of the antenna for a given frequency and that amount will vary from install to install . ground element angle/shape and curvature (on vehicles) can also greatly effect the performance and design of the antenna ......

    BTW ..... 102's typically had or have a spring or spacer under them to give a few extra inches to get closer to being resonate on the CB band . sometimes folks get lucky and find it is plug and play , and sometimes there's work involved ......
