Random long wire receive antenna

[Gord Neish]

I am looking at building a random wire antenna for shortwave listening (1-30mhz). I have a location that will allow approximately 80-100 foot antenna 20 feet high. The issue is my house is in the middle of this length, normal these antennas are end fed. What effect would it have if I connect my receiver lead-in in the middle of the long wire?

Than you'll have sort of dipole.
Just hang it and use.
I recommend to put some ferrite cores on coax at feedpoint and right before it enters to your home.

So if it was considerd as a dipole does that mean I need to place an insulator in the middle and twin lead or match to coax for the lead-in?

Insulator in the middle and just connect coax. Even 75 Ohm will work for you.
Also add 10-100 kOhm resistor between wires to cancel static electricity and ground coax before it enters to house.

Ok thanks for the input
