Whatever you're using for lead wire, make sure you think about impedance
matching. Twin lead is 75 ohm, coax is 300 ohm IIRC. Twin lead was used
with antennas on the old screw terminal TVs, and when coax, cable, and
new TVs came along everyone had a little dongle that not only physically
mated the TV to the cable, but also performed impedance matching.

Twin lead and coax are both susceptible to deterioration in the
elements; said deterioration causes substantial changes in impedance.
So, rule of thumb, if your wire is old and your reception is poor, get
*brand new* store-bought wire.

Yes, have it (impedance matching connection).

The direct-shot coax from the antenna experiment when installed new
antenna and doing the aiming, etc., didn't make any significant
difference before--I'm doubting it will now, either, but as said,
haven't done the experiment yet. That was unused coax, btw.
