Bev. Where you are, the FM reception is probably quite decent. Try just a reasonable length of wire to get you started.

It is impossible for anything digital to sound analogue, because it isn't analogue!

Poke the wire into the hole in the middle of the socket where the centre pin of the coax plug goes. Should work!

If you PM me with your address, Bev, I'll pop a 300 Ohm aerial (that's the plastic "T" ribbon) in the post to you. I have a spare, so you may as well have it. I don't think you will get anywhere using a length of coax wire as a makeshift aerial, unless you remove it from its braided wire sheath first. I think that sheath is designed to stop the wire picking up any airborne signals from outside. Cheers. Gary.

If just using wire make a dipole with dimensions depending on frequency of reception calculated here: http://www.procato.com/calculator-wavelength-frequency/
good result is had with either a 5/8th or 1/2 wavelength dipole - because you are maximising reception of the voltage leaving the transmission antenna
A dipole with 852mm in each half provides the lowest frequencies - as well as higher ones, but follow the calculator if you have a favorite station you
want to specifically receive.
A 300 ohm antenna follows a stated distance of one conductor to the next over the length of cable not spread out, vs a 50 or 75 ohm coax
that has a smaller dimension from inner to outer. The length not spread out then assists getting the signal from the section of antenna spread out
to your tuner. You can help by placing this cable on the right labeled antenna connection at the rear of your tuner.
Next,ideally you need to also know the stations polarity of transmission. in fairly flat areas it is likely to be horizontal, and hilly areas vertical. Some stations
waste enormous power trying to cater for both with what is called circular polarization . Accordingly orientate your antenna to suit their polarity.
If wanting many frequencies and omnidirectional reception and importantly an antenna with good impedance matching - which then maximises transfer across a
coax cable with stated impedance a discone is a good all round ( excuse the pun ) answer. Invented by Armig Kandoian they have many much needed
properties including dimensions less than 1/2 wavelength , 10 to 1 bandwidth and excellent impedance matching to 50 ohms which is the broadcast impedance standard.
Accordingly if using this antenna use 50 ohm coax not 75 ohm.
But for now a wire dimensioned correctly will do.

That's interesting. When I had an aerial out up I wanted a full element thing but the installer recommended a circular array due to the way stations are broadcast in this area. Which has a lot of hills and ridges. That must be why. He did explain but his explanation made no sense to me.
