Default Simple AM Loop Antenna?


"Bill" wrote in message
.. .
Thanks for the input Christopher I am indeed determined to build one.
I don't want to build a tuning one though. I am more interested in a
simple AM Loop that just connects to my radio to pick up AM broadcast.
These use to be popular. I suppose it was when radios first started to
come out. Anyways like I said they eventually were replaced by internal
Ferrite loopsticks. I suppose people did not like these big ugly antennas
on top of there radio. I don't think these old AM Loops had Tuners. And I
think they may have been spiral wound. You connect the 2 wires from the
antenna to the screw terminals on the back of the radio. But in my case I
would have to connect an 1/8 plug to plug into my Radio. I have no idea
what the size of the frame would be? How long the wire would be? and how
many turns around the frame to make? I have searched Google and have not
found what I am looking for there. I have found a couple of books but
can't afford the price tag at the moment. I don't even know If the antenna
I am looking for is even in the book. Here is a link to a few I have found
if anyone is curious.

If anyone else has any suggestions I am all ears. Or if you have any of
these books and could comment on it. I appreciate it.
Thank You Bill

Hello Bill,

Try -
http://rffun.com/catalog/mwant/4316.html

Variable caps are getting hard to come by, so a $49.95 to $59.95 price
for the completed project seems very reasonable. I purchased one of these
for my step father and it works great. You probably will not need a
direct connection to the radio, just place the Select-A-Tenna next to the
radio.

If you are determined to build one (as I was), just google
"AM Loop Antenna"
Lots of great articles out there.

Regards,

Christopher Cox

Hello everyone I am looking for detailed plans for an AM loop. I
will be using it only for one frequency 1370AM so I dont want any tuners
just a simple AM Loop antenna for my AM radio. I will have to solder a
1/8 plug to a 6-8 ft feedline to connect to my radio. It is a Kaito
portable model 1103. I want to built this AM Loop cause I listen to talk
radio alot and the static and other distant stations sometimes make it
hard. I have done alot of looking around on google searches but have
found no real detailed plans I am not sure if I should go with edge
wound or Spiral wound. Any info you guys can give especially a detailed
plan would be greatly appreciated. or maybe there is a website I may not
have seen you would like to suggest. I am sure I have seen most of them
atleast the most popular ones. Anyways thanks in advance for any input

Hi Bill

I built a couple AM loops last year. One is 4 feet on a side and the
other is 2 feet on a side. Both are made from PVC pipe and "hook up
wire". I can send you pictures.
If *I* was involved with the project of building this loop with you, I'd
sure try to get you to make tunable. Both of my AM loops are very sensitive
to getting the capacitor adjusted properly. I have connected the loops to
the receiver with two parallel wires from the antenna to the receiver.
That seems to work OK.

There is lots and lots of instructions for designing and building AM loops
on the Internet. From what I read, you are mainly interested in building
just one good antenna. You may not need a book for that.
