Firestiks are pretty ... even after peeling off their skin! A look at the Firestik brand antennas before they get their colors.
Important things that apply to all antenna models
The "KW" and "RP" series, trim to tune antennas are intentionally made on the electrically long side (favor lower channels) so they are well suited to installations with less than optimal counterpoise (ground-plane). On vehicles with marginal metal that the antenna can use as the needed reflective element, having additional wire will offer a degree of compensation. There is, however, a point where the vehicle fails to supply enough ground-plane for even one of these antennas (fiberglass motorhomes and vehicles, motorcycles, some ATV's and UTV's, etc.). In such instances, the only remaining choice is a no-ground-plane (dependent) antenna system that is comprised of a special antenna and matching coaxial cable. A common mistake made by the "newbies" is to see the tunable tip antennas and think that the "KW" and/or "RP" antennas, because they do not have a tunable tip, do not require tuning. Wrong! All antennas that are used on radios with the capacity to transmit a radio frequency must be tuned after they are installed. Failure to do so could cause damage to the radio.
The mechanical, tunable tip antennas, "FS", "FG", "FL" and "LG" series, make the process of tuning the antenna much easier. When they are assembled at the factory a tool is used to install the tuning screw assembly so they are "bottomed out" against the tuning extender. Before installing and testing the antenna, the tuning screw should be raised about half way up and locked down for initial testing. These antennas are designed using many decades of know-how and the mid-way point is a good place to start all testing and tuning.
