i did a little research and found out the k40 has 8 guage wire . and wilson only has 10 guage.i did this for just kicks but much too my surprise the k40 uses bigger wire. so now gotta ask will the larger wire of the k40 make any performance difference dale/a.k.a.hotrod cef426 cvc#64 454 [dx numbers] 38lsb

I got 50 more watts out of a Wilson 5000, which has 6 gauge wire compared to a Wilson 1000 which has 10 gauge wire using a Magnum S-6 350. |

How did you measure that? Your radio 'Mythbuster' since 1998

I had my meter hooked up with my radio in my truck and tried both antennas. |

So, your wattmeter was connected between your radio and your antenna, and it showed 50 watts more with the Wilson 5000 than it did with the Wilson 1000, correct? If that is the case, all your meter showed is that the Wilson 5000 had a lower impedance than the Wilson 1000. It does not mean more watts. Besides, measuring watts between the radio and antenna is only even close to accurate when the antenna is a perfect 50 ohm, zero reactance load. Your mobile antenna is not, I assure you.

All I know is it showed 50 more watts on the meter with the 5000 than the 1000, yes that's the way it was. From 375 to 425 watts.That's 50 watts in my book. |

Kashie - I could show you situations where a meter indicated an increase in power, yet there was less signal being radiated, and I am sure 833 could as well. Try this experiment. Place the meter in the coax between the radio and the antenna using a random length of coax (Total length radio to antenna). Make a note of the reading. Now replace the coax with a length that is exactly 1/2 electrical wavelength and note the reading. Replace the coax again with one that is 3/4 electrical wavelength and note the reading. All three will have given you a different power out, but which one is closest to being accurate? DO the same thing using the same lengths of coax but replace the antenna with a 50 ohm dummy load. Replacing an antenna with a different one, unless both antennas have exactly the same match ( resistance, Reactance and SWR) you WILL see a difference in APPARENT power. Please don't take this the wrong way both 833 and I are only trying to educate about things that both of us know well having worked in the industry for years - 40 plus in my case.

The experiment he proposes is an excellent teaching tool. I suggest you try it. 50 watts in your book is not 50 watts in the real world. All that means is that the Wilson 5000 has a slightly lower impedance. And, like Simon says, there is the chance that you are actually radiating fewer watts, not more.
