![]() "Lord Reginald Smithers" Ask me about my driveway leading up to my manor. wrote in message ... Kevin, Most handhelds will transmit power is between the ranges of 1 to 5 watts, the 1 wattage for short distances and 5 watts longer distances. Most Fixed mount VHF will transmit using at 25 watts of power, with a setting for low wattage 1 - 5 watts for short distance broadcasting. My understand is the Coast Guard will actually broadcast at a much stronger wattage than 25 watts and will have a tall antenna placed on the tallest land mass or building available. I have always heard that the low wattage handhelds will be able to receive the Coast Guard broadcast without any problems, but the Coast Guard will not be able to receive the low wattage units for anywhere near the distance of the higher wattage units. Kevin, if your theory is correct, why do the fixed mounted units use 25 watts, if the 5 watts are adequate to insure an adequate broadcast than can be received from the maximum distance of the LOS based upon the broadcasting and receiving antennas? If the 5 watts will travel just as far as the 25 watt broadcast? Why doesn't the 1 watt broadcast travel just as far as the 5 watt broadcast? I am always willing to learn, so help me understand the theory of low wattage transmission verses higher wattage transmissions. wrote in message oups.com...

The CG has a higher antenna and better receivers? |

Bill,
The signal strength still needs to be strong enough for the CG to receive the signal. Is it your theory that the CG can receive the 1 watt transmission just as strong as the 25 watt transmission because they have larger antennas and better receivers?

I was told by my friend, an electrical engineer with NASA, that the CG could
pick up the transmission on my 5w handheld most everywhere on Lake Erie. "Lord Reginald Smithers" Ask me about my driveway leading up to my manor. wrote in message ...

No, but bigger, better antennas help. How much power does a satellite
downlink use? "Lord Reginald Smithers" Ask me about my driveway leading up to my manor. wrote in message ...

Kevin,
The question is can he talk to the Key West CG? wrote in message ups.com... Bill McKee wrote: The CG has a higher antenna and better receivers? A friend of my brother's who lives close to the PA-NY border built a Beverage Antenna on his hill, and can receive CG transmissions from Key West, FL!! |

Kevin,
Since the frequency coverage of VHF is line of sight, was it a very very tall hill? wrote in message ups.com... Lord Reginald Smithers wrote: Kevin, The question is can he talk to the Key West CG? I'm not Kevin, idiot. |

Where they stack the beer cans into a tower? Then hook up the antenna leads to it? Cool. |
