Hi.
I am now planning to put up my first dipole for SWL.
I need help with;

1) A sensible length for general SWL.?
I mostly listen between 80 and 20 mtrs.

2) I would like a diagram of a 1:1 balun construction.
I believe this is the correct type for a dipole ?
I have a ferrite rod not rings, will it work the same ?

3) I will be using 75 ohm tv coax to its feed point which
is 90 feet from the house.
Will this be ok ?

4) I will need to bend the legs of the antenna to fit them in the garden.
I think this is ok for receiving ?

All help welcomed

Regards

Jeff
