Whip Antenna

You can sort of see how i did mine...
IMG_4834.jpg

Tooka piece of flat bar bent it to contour the bumper. Then drilled 2 holes, and bolted it on, then drilled another for the spring mount, i just ran my coax up under the tailgait over the weather stripping stuff...

Yes the coax is broke...this was after my buddy wanted to play tag...needless to say his little POS s10 has a big dent behind the door now...
 
Do you think tomorrow you could shoot some more pics of that?

and what size antenna are ya running

here's my 102" SS mounted to my rear bumper... I just drilled a hole, put the mount in and tightened the nut down on the other side... then the coax cable threads in from the bottom and the 102" whip threads in from the top...

The third pic shows my cb mounted... the brackets that come with the Uniden CB's align perfectly with some factory holes below the ash tray... the transfer case shifter handle hits the cb so I machnied a shorter handle to go in its place...

Sorry bud cant see the pics to cheap
 
Thanks Avery.

what up with the tennis ball?
And what uniden to you have in there is that a 78 or?

BTW Nice Rig
 
Uniden PC78 Elite... the tennis ball keeps the antenna from scratching the paint on my truck if the antenna flops around...

thanks, its a work in progress :)
 
haha of course it works...the antenna doesn't have very much surface area so the wind doesn't really whip it around too much but on the freeway it gets going sometimes (not a lot but enough to move that couple inches and hit the bed above the tail light) so the tennis ball just protects it...
 
I got one of those radio shack 90deg clamp-on mount and a medium spring and tossed the clamp part and drilled a hole in the center of the mount for a bolt (hidden by the antenna connector) and used the existing body hole for the corner trim. I then drilled one small hole in the upper left corner and inserted a bolt to keep it from moving side to side and from that bolt, I have a braid strap to the body and frame mounts below. Works fine with the whip just use a tennis ball to protect the body.

Spring on a 102"?

Since the entire antenna is a giant spring, why add one? Seems like they would just whip around and hit body panels more then needed.

As for the 102" whip with a gutter clip, I would comment about mixed polarization, but only Pauly and a couple of others on the site would understand what I'm talking about. The military did it on purpose on some of their vehicles, and it works quite well.

while you lost me.

Are the whips flexable enough to use a gutter clip without the spring?

The 102" are pretty flexible and actually dont require a spring. I would hesitate using a gutter clamp with a 102" due to the physical loads at the base. I would be afraid of ripping it off.

No matter where you mount the antenna on a blazer, your going to wind up with distorted radiation patterns and very low efficiency at these frequencies. Due to ground and structural reflections and multi-pathing from nearby buildings or mountains, the polarization will be anything but pure vertical and omni-directional. Just find a place where you wont rip the antenna off, install it, tune it and go. Its only CB.

I agree with that - the antenna would be gone on the first trip! What I was refering to was using a body mount, then puling the antenna down with a gutter clip so it forms an inverted U. Doing so gave the antenna both horizontal and vertically polorized radiation, making it more effective for ground wave propagation on the lower bands. At 11 meters? I don't know if it makes any difference.

Amen! It's a 4 watt AM radio. Use a good base loaded 5/8 wave antenna - mount it smack in the middle of the metal part of the roof if you wnat the best signal, otherwise mount it on the hood. No, it won't give you hte best radiation pattern in the world, but your not driving it with an IC-7000 either!

Yes , you can certainly use it bent over and lashed to the roof on the truck :D

Yes, as long as the tip is isolated from the truck, when lashed, and not shorted to ground :doah:
The top part of the antenna has little radiation anyways cuz its the high-voltage part of the antenna. The high current part (lower half) does most of the radiating. I use the whip on mine if im going to the sand dunes so I can attach a flag, otherwise I use the shorter, loaded one for everything else.
 
Yup of course not touching . When the whip is vertical , it has good low angle radiation , great for long distance work ( thousands of miles when sunspots abound )

Lash it down , and it becomes a great NVIS ( near Vertical Incendent Skywave ) antenna , going straight up almost vertical , and coming back down to work local stations ( 3 to 5 hundred miles in good conditions ) .
