John H. wrote in : Another question: Most antennae seem to come with about 20 feet of wire. Mounted on a console with the radio right there, I could get by with about 3 feet of wire. Is all the extra wire necessary? No, it's not. If you're not a solderer, find someone who can put a new connector on the radio end of your cable or make up a new cable. The Metz does NOT have a cable attached to it....one of its great features. YOU put the cable on it so the cable can be replaced....not hard wired into the plastic, like the little whips from Shakespeare come. The farce of "tuning" the antenna with cable length is nonsense.... True, you don't "tune" the antenna with cable length, but you need a certain amount of it to properly tune the antenna. My memory is rusty and I'd have to go dig out the books, but I think you should have a 1/2 wavelength or so in cable length. Maybe it's a 1/4 .... can't remember. Too short will cause the antenna not to load properly (assuming it is the correct length) and result in an excessive SWR value that reduces effective transmitted power and, in the worst situation, cause damage to the output stage of the radio. If you have matching problems with the antenna and are fairly certain that the antenna, connectors are known good and the radio is presenting power properly, then the suspect is the length of the feedline. End result - you trim the feeline to bring the antenna to the correct match. Thus you are tuning the antenna using the feedline. That's why God invented antenna tuners. :) That is the beauty of rec.boats, even when you think every possible boating discussion has been beat to death, a new informative topic will arise, that we can learn from. Of course, we will beat this one to death. Well, it's not beat to death yet. I'm getting conflicting views on this antenna cable length. I really don't like having 20' of cable coiled up in the console. There's not much space there already. But, I'll do what I have to do. |

Agreed - if it's really bothering you that much, do as Dick suggests. Sometimes people with some knowledge can confuse the issue for those with less than perfect knowledge. I'm as guilty of that as anybody. |

I used to be able to rattle stuff off as quick as I could talk - after a few, well more than a 'few", years away from the radio and building "stuff", the more I seem to need refresher on. For example, I fired up the Collins S-line the other night just to hand out some Qs for a state CW contest that was going on and I had to look up how to load the transmitter properly. Used to do that in my sleep. :) |

Now the antenna choice is narrowed to either the 5242A or the 5247A. http://tinyurl.com/yuqaux As they're both the same price, I'd guess the '47 would be the way to go unless I'm missing something. Thoughts? |
