Default Grounding

Will be using a long wire strung around inside of the house for now when I
get my tabletop. Where the radio will be there are no pipes etc, what is the
best way to ground, can I use the center screw of the electric outlet. Been
using protables now & a set top with a whip built in antenna (RS394).

Only if your mains wiring is in metallic pipe or raceways. Otherwise
I'd run a discrete wire.

Is there any where in the house or must I attch to a metal stake in the
ground. Would rather not run the wire outside,

Default In-Door Horizontal [Flat] Loop Antenna - - - No Grounding Required

SR,

Vice using the questionable the Ground {Green Wire} of your
Household AC Power System.

Why not consider a simple Around-the-Room {Ceiling Level}
Horizontal [Flat] Loop Antenna. The Loop Antenna is consider
a 'blanced' Antenna that does not require a Ground and is
Horizontally Polarized so it generally pick-up less man made noise.

The "In-Door" Horizontal [Flat] Loop Antenna is easy to build;
usually is relatively long 40-60 Feet for an In-Door Antenna;
and relatively lower noise pick-up to an in-door vertical antenna
or long wire antenna.

The Radio or Receiver can be run off of AC with an AC Ground
connection via the AC Power Plug or DC without any Ground
connection at all.

something to consider - iane ~ RHF

RHF,

This is the first time I recall you *not* posting a link to materials/instructions for
building the antenna you recommended in your reply.

It seems like one I've seen you refer to previously, but darned if I can find it in my saved
newsgroup messages.

Default In-Door Horizontal [Flat] Loop Antenna - - - No Grounding Required

The loop will be unbalanced if you don't use a balun. Of course, my
solution is to buy the Wellbrook ALA100.

At 40ft of wire, I find two BCB stations about 20 miles away force my
7030 to switch on the attenuator. I have maybe 10db before the s-meter
is pegged, so I wouldn't go much beyond 60ft if you get the wellbrook.

Default Quest: Connect End Of Loop To Beginning ?: In-Door Horizontal [Flat] Loop Antenna - - - No Grounding Required

Hi,

Question re the "loop"

Would you connect the end of the loop to the beginning, thus making a "true
loop" up there, or just leave it
open at the end ? Why ?

What is the effect of the vertical run down to the receiver ?
Would you suggest coax for this vertical section, or usually not necessary ?

Bob

Default Quest: Connect End Of Loop To Beginning ?: In-Door Horizontal [Flat] Loop Antenna - - - No Grounding Required

Robert 11,

THE LOOP ANTENNA ELEMENT :
The Loop being a Square/Rectangular Shaped Loop completes the
Circling of the Room around the Four Walls. Both Ends of the Loop
come together at some point on the Wall or at a Corner of the Walls
near the Ceiling and are connected to a Pair {Two} Parallel Wire
Feed-in-Line that goes down to the Radio's Antenna Input.

THE FEED-IN-LINE :
The short vertical Feed-in-Line for this type of In-Door {In-the-Room}
Loop Antenna is usually a Pair {Two} Parallel Wires.
* 300 Ohm TV type Twin Lead works well as a Feed-in-Line
for this type of Loop Antenna.
* Speaker Wire also can be used; either flat or twisted will work.
* The basic wire used to make the Wire Loop Antenna Element
can be continued as a single piece from the Radio up the Wall;
around the Four Walls; and down back to the Radio. If this is
done then it is recommended that the short vertical parallel run
has the two Wires Twisted together.
* A piece of Audio Coax Cable can also be used; especially if
the Radio uses an 1/8" Mono Jack for the External Antenna Input.


WANT A BIGGER LOOP ANTENNA - PUT IT IN THE ATTIC :
[ When an Out-Side / Out-Doors Antenna is NOT Permitted. ]

KISAP: I recommend using TV type Antenna Parts for most
"In-the-Attic" Antenna installations.

* 75 Ohm Coax Cable for the Feed-in-Line for Household
'man-made' Noise RFI/EMF Reduction.

* TV 75 Ohm to 300 Ohm Matching Transformer (Balun) for
Noise RFI/EMF Reduction and AM/MW Band Signal Reduction.

* TV 300 Ohm Twin Lead for the Wire Antenna Element
50-100 Feet -or- 90 Feet of Insulated Hook-Up Wire.

* "F" Jack to 1/8" Plug (1/8" Mono-Jack Adapter)
RadioShack Catalog # 278-257

Default Grounding

Dear Steve,

If you run any kind of wire in your house, you probably will not need
any grounding at all. Just to check, however, try the radio without
grounding at first and then try hooking up a ground and see if there is
any improvement or any difference at all. (The ground on your
electrical outlet is fine for this experiment.)

RHF and BPNJensen's posts are also correct. A loop antenna used inside
a house may give better performance than just plain wire run randomly
and loops generally need no grounding.

As a matter of fact, in my personal experience, a loop antenna, indoors
or outdoors, will afford much better reception quality (S/N ratio) than
long wires in areas where there is a great deal of local electrical
interference as loops tend to "reject" such interference.

You might want to try to make (or buy) a loop antenna and mount it in a
window. There are several sources on the web for instructions and a
very good book is Joe Carr's LOOP ANTENNA HANDBOOK.

Do try a good antenna on your Satellit 800. I think you'll be very
pleased.

Best,

Joe
