If you have a adjoining houses, I would advice to not hang the antenna on the
house, as you might cause TVI. I would hang it on the tree. Even it it is only
10 feet from the house.

On 16 Nov 2005 05:21:44 -0800, was heard to say:

I live in a deed restricted community where CB antennas are not
permitted to be erected. I need a low profile antenna - one that will
not bring attention to the homeowners association. I want something
better than an indoor antenna. I was thinking about one that I can
just put out on the grass in my backyard like on a ground plane or
something. I want to talk. Any ideas?

I think you might be misunderstanding the meaning of a "ground plane"
antenna...

You might be able to get away with a vertical dipole. You could
attach the dipole to a corner of the house, running it along a
vertical seam (and AWAY from any downspouts) so that it would be less
noticeable. Feedline can be concealed beneath siding in many
instances.

Basically your antenna will consist of two pieces of wire (insulated,
please, other than that it's not important what type) that are 104
inches in length. One wire will be attached to the center conductor
of your coax, the other to the braid. Arrange the wires so they are
in a "T" configuration in relation to the feedline. Hang the antenna
so that the wires are in the vertical plane. It's as simple as that.

Beware of foil backed Celotex in newer homes, not good for reflected power

If you was to save some money, just use the coax itself as the dipole. Once you
separate the center wire from the braid, that is the star of you dipole. That
needs to be about 102-104 inches long. The center wire is easy, but separating
the braid is a pain in the ass. So cut about 1 inched of braid, and solder a
wire to the braid, like 14 gauge from Home Depot. Remember, the length should be
cut long, and then cut shorter to match up and get low SWR. Is alwasy easier to
cut shorter, and to make longer.

I can't stress how important impedence matching is to your antenna system.
I'd rather have a 1.5:1 resonant SWR then 1:1 unresonant SWR. Think about
singing in the shower. There is a pitch that sings back to you with very
little power. That is what happens in a resonant antenna. Recieved signals
also get this natural amplification. Frequency is unimportant to this theory.

Excellent links. I was looking for a winter time project, looks like I might
give this a try.

Linky no worky.

Worked yesterday. Try again later.

What's wrong with sticking a 1/4 wave or 5/8 wave loaded verticle into
the ground. Bury a couple of radials in the ground. I have a 5BTV
verticle bolted to a pipe I stuck in the ground about 3 feet. Been in
the ground for a couple years and works very good on 10m.

Hang a flag at the top and there ya go - it's a flag pole.

Just say 'NEO'

Works now.

Yep it does, one looks close to the one i made a couple days ago.. Mine
is prettier
