How would I go about making a cheap, easy cb antenna for a base station
at my house? How far would it need to be from my 2 meter antenna? Could I make a whip by cutting an aluminum 3/8 rod to a 1/4 wave and thread the end to go into one of those 3/8-24 so239 mounts? |

You can but you will need 1/4 ground rods at right angles to the vertical
radiator. Four is prefered. wrote in message oups.com... How would I go about making a cheap, easy cb antenna for a base station at my house? How far would it need to be from my 2 meter antenna?

Or, for 27 MHz, just use a 1/2WL center-fed dipole with no radials. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

you've no right to be using a 2 metre radio, if you don't know the
fundamentals of building a simple antenna. seems amateur licences really do come from Macky,deeeee's these days. |

Why are the ones you buy dont have ground radials. Like the "sticks"
they use on trucks? I am guessing they are 5/8 wavelength and have some sort of coil inside them I cant see. I am not wanting "super performance" But something that is decent. |

If you had a copper roof, you wouldn't need radials. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

Used to be, exams weren't made "public". The FCC would give you a hint as to what "may" be asked, but not a list of questions with answers. I still have a copy of one of their "study guides". A single sheet front and back usually. Unless you knew electronics, you rarely passed. Then along came some wizard who thought the tests should be dumbed down. Now you have the books with all questions and answers. That sort of test taking does NOT prepare someone for the field. Any idiot can remember a bunch of answers after a couple hours of going through the book. It does NOT "teach" anything. I know some "hams" who don't even know what the hell a fuse is for. Imagine that! It isn't the person's fault, their acquiring the license via the current system is just the way it is. But, that should not preclude them from picking up some books to "READ" about such things as antenna theory, building basics, etc. Without looking at some books, they'll be forever asking questions and not understanding. The Internet is a wonderful source of help, but there is only so much you can do. You need "reference" materials to get you going. READ BOOKS - THEN if you still have questions - ask........... The questions asked, should be the fillers - not the main content. cl |

Take any good 10 meter design -- and lengthen the elements OR a 12 meter antenna and shorten the elements. Standard theory here, found in any Radio Handbook (ARRL, RSGB, Bill Orr) Library has copies or can get you one from their network. gb |
