subbing for antenna wire

My tuner went down and has been removed for repair. Meanwhile I'm using a receiver (record out) for a tuner. It does not have the same connection for the antenna so I'm having to improvise and in part I'm using an inch or two of standard speaker wire between the antenna and the receiver. Should I bother to grab some actual antenna wire somewhere to switch out with the speaker wire?

Any wire is fine. try to space it the same as the antenna wire (if it is twinlead)and you will be perfect.
Use some packing tape if you have to, to keep the wire spacing the same.
If it is coax, do not worry about it if yyou got a signal.
If poor signal, you need a small cheap transformer.
