Antennas are tuned devices, and as simple as they look, they have to be
properly constructed. Get some books on antenna design and start from there.
The ARRL Antenna hand book is a good start. It is distributed by the Amateur
Radio Relay League. Your next step, will be to understand the contents of
the book.

The simplest antenna are a pair of wires cut to the proper length, and fed
down a properly matched coax cable to the receiver. At the receiver end, a
proper matching coil is used to match the antenna impedance, to the
receiver.

Your best solution, if you are not familiar with antenna design, and want a
fast working solution, is to go to the local Radio Shack and buy the
necessary pieces you need. This should work for you.

I live out in the boonies and it's hard to get decent Radio stations,
especially since I live in a home with metal siding and roofing.  I
dont want to spend anything on this project, just use some of the odds
and ends I got laying around, and plan to put this on a board and
mount it outside with coax coming in the house.
I found the simple plans on this website.

The only problem is that I dont have any of those ferrite rods or
toroids.  However, I got one of those outdoor converter devices for tv
antennas that have 2 spade clips on the wires on one end, and a coax
connector on the other.  (made to convert a tv antenna to coax).  Can
I just hook the two wires from this converter to the two home-made
antenna wires and run my coax into the house?
And, just for the heck of it, I have an old busted tv antenna.  Would
it work to use 2 of the "rods" from the antenna (length as shown in
the website), and screw them to a piece of plaxiglass in the middle as
an insulator?  That way I can mount it on a nearby tree.
Thanks all
