Im needing help with instructions and especially pictures on building A Quik and E-Z Ham Radio antenna ---PLEASE

I'm trying to find an instructable showing step-by-step, coming out of a HAM RADIO to a home-made Antenna. So far, all I have is the plug that screws( Where the Antenna plug screws on) on to the back of the mobile unit itself. The plug used to go to a magnetic antenna , but I cut that off because it was broken and wire was fraid in two peices. SO, like I said all I have is that screw-on plug, that needs to somehow connect to wire? and on to the Antenna, but not sure where to Begin. Any Help would be appreciated. Not looking for the Best antenna, I'm looking for something Fast and E-Z to build, to possibly get my radio out and too just listen, then of course I have to be licensed. Remember something FAST ?

The frequency is VHF FM mobile ham 2meter, like i said something simple? It is like I asked to build a Rocket, I just wanna build a simple antenna out of the connector to like cable coax( simple TV cable) and 10 guage wire and a coat hanger...... Any Ideas?
RG-58, a through chassis connector for SO-239 at radio shack, some brass welding rod cut to 19 1/4 " for the vertical element. Take small nuts and bolts in the holes in the connector and bend brass rod around them. Might help to heat the rods to cherry red for the bend. Bolt 1rod for each hole then cut to 18". Measure not from the nut but from the base of the vertical for the cut. This antenna is good for transmitting around 146.000. Are you a ham?

TV Cable - (300 ohm twin lead, the brown ribbon cable)

(As an aside, you can do the same thing by folding a piece of regular electrical wire in a u-shape and connect the wires in the same fashion. Just use a piece of PVC or wood dowel to keep it's shape and tape or use electrical cable ties to secure it.)

1. -Measure out about 54 inches of twin lead cable. On one end, strip the insulation back about 1 inch, leaving the copper conductor exposed. tie the ends together and solder.

2. about 1 1/2 inches above that, carefully cut away the insulation on both sides of the ribbon cable to expose the copper. Leave this for now, we'll come back to it in a moment.

3. On one side, cut through the wire 19 1/2 inches above the area of exposed copper that was done in step 2. About 1/2 inch above that cut, make another cut, and remove the piece, but do not disturb the other uncut side.

4. Get the coaxial cable out, strip the ends so the braid is separated from the center conductor insulation about 1 inch. Expose about the same amount of center conductor, and spread the center conductor and braided shield apart.

5. Solder the center conductor to the exposed area on the long, uncut side of the twin lead cable.

6. Solder the shield to the exposed area on the short side of the twin lead.

7. Punch a small hole in the very top of the twin lead ribbon in the middle between the copper wires, and loop a piece of string through the hole. This is what you will use to hang the antenna up with.

This is the fastest antenna, not the most efficient.

Also, if you have no callsign, you shouldn't be transmitting.

Here is more info (with pictures!) on how to build this type of antenna - http://www.harfordemcomm.org/files/twinlead.pdf

I've built many different types of VHF antennas for amateur use, and this was my very first antenna. Also, if you can get to Radio Shack, get a coaxial clamp-on ferrite choke, and clamp it about 6 inches below the connections on the antenna. This keeps stray RF from traveling down the outside (shield) of the coaxial line.

If you want something even simpler, strip a piece of coaxial wire about 19 1/2 inches, peeling the shield down, back over the cable, exposing 19 1/2 inches of center conductor. Eureka, a simple Dipole!. Remember to hang it straight up and down. And get a Ferrite Choke from Radio Shack to snap on the bottom of the coaxial cable about 25 inches form the top of this antenna.

P.S. - The reason I asked what frequency/band your radio was, is that this determines how big/long your antenna needs to be in order to work properly, and to keep you from damaging the radio.

I wan't trying to be a jerk, but want you to enjoy your radio and the hobby for a long time. A little patience goes a long way, and the frame of your request was vague, especially when some antennas go as far as 250 feet long, down to less than 2 inches.

I hope you enjoy the hobby as much as I do.

Oh, boy. Where to start.

OK, what frequency/band are you talking about?

Since you were so forthright in asking what you wanted, I offer this website:
