Testing the popular fiberglass antennas showed some brands insert losses, like a dummy load, to make their antenna look good on the SWR meter, but sacrificed most of the power gain.
Wilson designed the Silver Load, with its exclusive impedance matching transformer, to give good SWR without sacrificing power gain. Additionally, using spaced windings on the top load to eliminate the dielectric losses, and silver plated wire for maximum radiation, Wilson has the best performing fiberglass antenna available.
Tested by Dr. Dwight Heim
Dr. Dwight Heim, ( PH.D. Electrical Engineering, Professor Emeritus, University of Michigan ) an independent consultant, conducted a test and comparison on some of the fiberglass antennas used by truckers. The graphs below indicate the results of this comparison test.
 |
The Wilson FGT-2, 2' Silver Load antenna out performed the Firestik® 2' and even the 3' models of the Francis and K-40 fiberglass antennas. NOTE: Relative dB gain figures shown for this chart apply only to antennas within the 2' antenna test comparison, and do not apply to the other charts. |
 |
The Wilson FGT-3, 3' Silver Load out performed all other 3' antennas tested by a wide margin. Proof that the Wilson Silver Load is the most powerful 3' fiberglass is hard to beat. NOTE: Relative dB gain figures shown for this chart apply only to antennas within the 3' antenna test comparison, and do not apply to the other charts. |
 |
Once again, the Wilson FGT Silver Load series of antennas outperforms the competition. The FGT-4, 4' antenna proved to be the better performer against the other 4' antennas. NOTE: Relative dB gain figures shown for this chart apply only to antennas within the 4' antenna test comparison, and do not apply to the other charts. |
TEST RESULTS: The test results and charts above are based on all CB fiberglass antennas tested by Dr. Dwight Heim.
PERFORMANCE GUARANTEE: The Wilson Silver Load FGT fiberglass antenna will outperform the fiberglass antenna it replaces or your money back. This guarantee is good for 15 days from the date of purchase at the original purchase point only, and with dated sales receipt.
ANTENNA POWER GAIN : the amount of improvement in power amplification over another antenna. The higher gain antenna will transmit & receive farther, but the actual distance will vary depending on the gain, ground terrain and other environmental factors. Individual test results may vary due to the vehicle's ground plane and matching configuration.
EXAMPLE :The Wilson X has 20% more power gain at 27.185 MHz than Brand X antenna. This means that if the Wilson transmits 100 watts of power, then Brand X will need 120 watts of power to have the same signal strength at the receive end.
Wilson "Silver Load" FLEX Fiberglass Advantages
Adjustable tip for fine tuning SWR & resonant frequency Exclusive impedance matching transformer lead 1/4" tapered fiberglass rod Fully linear top loaded for maximum transfer of power
out of antenna ( better than helical winding )Spaced windings to reduce dielectric heat loss 22 gauge silver plated wire to reduce resistive losses Special rubberized covering for weather protection Static reducing weather cap 3/8" X 24" standard threaded mounting Weather Channel Ready Available in Black only Sizes available: 3', & 4' 1 Year Warranty
Patterned after the proven performance of the Wilson FGT fiberglass antennas, the Wilson Flex antenna out performs all similar types of top loaded flex fiberglass antennas. It is designed specifically for the CB user requiring an antenna that will take the rigorous vibrations from a truck, handle rugged use, the extreme changes in cold weather, and still perform well.
Wilson uses larger 22 gauge silver plated wire to provide more efficient operation on small diameter forms. A special weather resistant rubberized cover is used to maintain flexibility. The tapered 1/4" fiberglass rod is more expensive to use, but offers the durability that is required from this type of flexable antenna. With the tunable tip, and the exclusive matching lead, you can easily tune the Wilson Flex for a low SWR. The Wilson Flex antenna is available in both 3' and 4' sizes.
The Wilson Flex antenna has a 15 day money back guarantee and a 1 year warranty.
PERFORMANCE GUARANTEE: The Wilson Silver Load FLEX fiberglass antenna will outperform the flex fiberglass antenna it replaces or your money back. This guarantee is good for 15 days from the date of purchase at the original purchase point only, and with dated sales receipt.
