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.

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

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.

Depending on the deed restrictions, even a flag pole may require an
architectural committee to review the plans before erecting even a
flag pole.

Right now the best antenna to put up for VHF use is a log periodic
that can look like a TV antenna. Some deed restricted associations
have so poor a turnouts for yearly meetings they cannot alter rules
that have been nulled by federal regulations. The Communications Act
of 1996 strikes down the blanket "No outside antenna" restrictions.
Associations should have gone back and altered restrictions to
prohibit outside TV antennae and restrict other antenna systems for
amateur and cb radio.

If they have not done that, then technically there is no antenna
restrictions. One should check their deed restrictions and updates and
confirm anything with a lawyer.

James,

Checking with a lawyer is probably good advice. Lotsw of verbiage that
only other lawyers can easily understand.

I would think that if a federal regulation were to have the effect of
'nulling' a local ordinence then there is no reason or need for the
local committie to 'alter' their regulations. They're already altered
by federal mandate. No? I think you may have a valid point somewhere
in there, but it escapes me. What are you saying?

I live in a neighborhood that in the past has had deed restrictions.
In order for the restrictions to survive there would have had to have
been a vote taken and a board installed. This would have had to have
taken place within one year of the last parcel of property being sold.
Didn't happen and I have an antenna farm on my property.

And - Since when have we moved CB into vhf spectrum? Wasn't OP
talking of erecting a CB antenna? Where did VHF log periodic come
from? Is this part of the point that I can't quite get a hold of?

In the UK I believe even putting up a TV antenna is against the tenancy
rules as some, especially in flats, have to share a communal aerial. I don't
know if its different in the States.

Bob,

I have the 5BTV too, and love it. But if he is using it for local, forget it. I
have am Imax in a tree about 36 feet high, and the 5BTV ground mounted. The 5BTV
gets out all over with DX, but is terrible locally because it is ground mounted.
