Thank you for the solution to a problem I did not
realize I had. One of the pleasures of QRP is low
power levels. One of the ways to get a greater
bandwidth from a dipole is to make it a folded
dipole. A great way to feed a folded dipole would
be with a "TV" balun.

Tom,

The dipole is a balanced antenna, fed at the

center. Stricly speaking, you
should be using a 1:1 balun to connect to an

unbalanced feedline. However,
no great harm comes if you just connect it to

the coax directly. DO NOT use
a standard TV/FM balun, they are 4:1, and you

are better off with it just
like it is.

I have one question about dipole connected to

grounded receiver.

I've made dipole antenna. One "pole" is

connected to center line of coax,
the other to shield line of the coax. Cable

goes down to receiver and
connects with BNC. The BNC is (of course)

connected to case. The case is
grounded.

Can someone tell me, what is te purpose of the

dipole if one of the poles
is
grounded? I mean, why i built two poles when

one goes directly to
ground!Shouldn't it be easier to build just a

monopole? I'm puzzled....

Thanks in advance
