vertical dipole?
 

Hey kids..I know gap kind of does this..but anyone think a verticle dipole
would work...basically a vertical fed in the center...Im wanting a good 10
meter antenna for local stuff and was thinking about a conventional
vertical..than I thought maybe I could do without the radial system and ground
loss issue but just putting up a vertical dipole for 10...any thoughts??

Have built several of these -- works great -- just run the coax at 90
degrees as far as you can from the center feed point OR consider using a
coax choke or balun.

Yeah, exactly what i was thinking of building...was just gonna string wire up a
tree...will probably have to run the coax parallell to the lower half of the
antenna though...wonder what effect that will have?? Thanks again for the
info..

Yep, had one here also. Works OK, but don't get it too high above ground. I
hung mine from a tree limb about 25 feet up at the top and tied it off to a
brick with some rope at the bottom. When 10 was open it worked quite a bit
of DX with 100 watts, but what doesn't on 10 when it's open :+)) .

Hi Steve,

There are two ways to accomplish this.

1.) Simply run a length of coax directly up. Strip back the shield
to expose a quarterwave upper element and in the stripping back of the
shield, actually roll it back over the jacket below it to serve as the
lower element.

2.) Use a quarterwave length of tube as the lower half, run the coax
up its interior, connect the shield to it at the top of the tube, and
continue the inner coax up another quarterwave.

Hi Richard, sounds like a good idea...thanks es 73's de kb8viv

This sounds like the simplest way. He could use an 8 foot piece of 1/2 in
Al tubing for the lower element.

I would put the thing as high as you can. For locals, you *want* a low
radiation angle.

This looks like a good plan:

How about a J-Pole? Low angle radiation. The bottom end can be connected to
earth ground. In fact, I constructed one using a mast with the 1/4 wave
parallel section added 1/2 wave below the top. Real easy. No radials.

Just a thot.

thats also an option..i wonder if'n I'll need radials with a vertical dipole??
