New to the group
I just joined the group. I have built a Magloop for 20 and 40 meters
and it's great for taking camping! It is made from 20 feet of old RG-
8 coax which I am using the shield for the element and an

LOOP antenna theory
Will someone direct me to any write-ups on basic vhf rdf loop antenna
theory? I want to find out how to best use a 6" diameter loop antenna
with my handheld vhf reciever to locate signals in Search

Re: " Please add me back to the list"(of BPL police)
Or....
Just do your ham (and SWL) friends
around the globe a favor. Set up a
"Beacon" station of a few watts or more.
That should help....
with everything, for many miles around.

Re: Please add me back to the list
Wireless DSL??? First I've heard of that one. I would say that if
you're hearing it on the FR-200 there's probably a Part 15 violation
going on. It's probably being radiated from the telephone lines

Re: FM loop antenna for nulling
Tony, I took a folded dipole, (one using coax) opened it up and put it
in a hula hoop. It works well for me, especially on radios that accept
75 ohm inputs. An impedance matcher allows good reception

Re: FM loop antenna for nulling
TONY,
Instead of a Loop Antenna, try using a basic (Ready Made)
300 Ohm TV Twin Lead "FM" Folded Dipole Antenna.
(Cost about $3)
The FM Folded Dipole Antenna can be layed out Horizontally

Re: FM loop antenna for nulling
These kind of antennas for the 3meter band (88-108 MHz) are usually not
called loops but square dipoles. If you make a metal square with sides of 50
cm., slit the bottom in in the middle and connect

Re: FM loop antenna for nulling
Tony,
You could probably use the same construction method
and calculations used for MW and LW loops but the
problem you might have is that the Q would be too
high. AM signals found on MW are about

I wanted to know if there was any way to design a loop antenna for

Re: Kiwa loop
Signals frequently come in at an angle. The ability to tilt the loop
gives you the ability to capitalize on this phenomenon. Often you
can get a higher peak or deeper null with a tilted

Kiwa loop
I have noticed that the Kiwa loop along with other loops can be
tilted in the axis of the null. Does this help to increase the null
of certain stations or does it have another purpose? Maybe null

Re: Fractal antenna
Lupu,
A VHF/UHF fractal antenna is a very, very small animal indeed!
Dimensions and angles are extremely critical.
