Has anyone used any of the mic. adapters that Copper sells and how well do they work? Also does anyone know if they have an adapter to go from a Galaxy Melaka (4pin) to a D-104 wired for a 5 pin President Madison?(or vicey-versey as it may be) |

Bullseye,
YES, they work very well.
YES, I use them every day.
PLEASE, check out my Review on them in the SUBSCRIBER PREVIEW SECTION, Product Reviews, Microphone Adapters.
If the MELAKA is wired the same as other Galaxy Bases (same wiring as) COBRA/UNIDEN Radios then the Adapter you need is listed below.

I have never worked on a Melaka so Iam not sure of the wiring on it.
A suggestion, get the whole set and it will save you a lot of time in the future.
Maybe the Forummaster can make a "Forum Members Only Special" on the complete set.

i converted all my radios to 4 pin uniden. these adapters work very well. |

They work excellent, and you can save a hell of a lot of money on mics. Everyone is always partial to one mic and these adapters make it possible to use it on a number of different rigs. I have a HTX100 converted to 11 meters and lsb, a Galaxy 959 and a President 2510 and run the same D104 Tug9 on them most of the time giving credit to the various adapters I have purchased. The only problem that I have ever had is that sometimes they get a little loose after using them often. This was quickly cured by taking them apart and filling cavity with epoxy. |

Re Smor...
Several things make an antenna have wide band width. BUT first a definition of wide band width so I do not confuse anyone. Wide Band Width is the amount of frequency coverage an antenna will allow the user to utilize with a satisfactory SWR.
The band width is dependant on several factors.
One is the diameter of the radiator. A small narrow wire will have a smaller band width comparted to that of a larger diameter aluminum pipe. A little trick the ham people use to create a bigger profile radiator is a cage. A Cage is nothing more than 3 or more wires all of which are connected at each end and separated in the middle by insulator spacers which spread out the wire to create a bigger cross section.
A second method is the type of antenna. For example a full wave loop antenna has a very wide band width becausethe radiator is longer. This type of antenna by its very design and construction has a large band widtth.
Another antenna that has a very large band width is the Folded Dipole which like the loop antennas get their broad band ability by their construction and design.
THIRDLY and most importantly. Antenna Length. A quarter wave length antenna aka 102" steel whip with a 4 inch spring can cover the entire CB spectrum due to its long length and easy matching quarter wave length. A base loaded short trunk mount antenna needs coils and caps to tune the antenna and in doing so restricts the compatibility of the antenna to ranges determinable by the value of the coils. Electrically Short antennas are notorious for having a very small band width.
Boiled down to its essence, for CB use a 102" stainless or fiberglass whip for the best results. |
