Radials are better than a ground rod and no sledge hammer required.

If I run a wire out the window to a tree near the house, do I also

Does an outside wire perform better if it's grounded or is it a safety
precaution (or both)?


It's mainly a safety issue, since you can't make a good RF signal ground
for the type of antenna you're considering (random wire or inverted-L),
*unless* you use the technique on the following website:

http://www.anarc.org/naswa/badx/ante...e_antenna.html

An RF signal ground needs to be short. Several feet of ground wire is
too much. That's why the grounding method on the website (above) works
so well. The ground wire to the rod is very short. Mine is about
12-inches.

Even if you're not interested in reducing noise with a good RF ground,
it's still a good idea to have some kind of ground for lightning or just
static electricity. I suggest you install a ground rod near the location
where the antenna wire comes inside the house. Connect a lightning
arrestor between the antenna lead wire and the rod. Better yet, build
the antenna design on the website above. This method helps to reduce
noise from domestic appliances such as televisions and computers.

I back this statement 100 percent. A different location, a different
antenna, different soil conditions, all lead to different circumstances.
Experimentation is the proper approach here.

If you really want a very quiet antenna that performs. Try building
a EWE antenna and purchase a ICE 180A Beverage Matching Unit.
You won't be disappointed with this arrangement.


Take a look at the sites I have listed.

Regardless of which antenna you choose to erect outside it will build
up some electricity from wind or at worst lightning. Your antenna is
grounded one of two ways:

-Via an external ground located outside attached to the antenna.

-Via your coax lead into your house, then through your radio to the
grounded electrical outlet. This then proceeds to the panel which
distributes electricity to your house.

Should you have a build up of significant current from wind or
lightning which ground would you prefer? The current has to go
somewhere, I would encourage you install a ground outside. It may
even be required by law depending on where you live. I know many
websites have been forwarded, try this one, there are some excellent
grounding documents:

Hang in there buddy, I know it is alot to digest but learning is half
the fun.
