Hi and welcome to the Phorum.
A long wire antenna is directional but radio waves are hitting the wire from all directions, the ones from either end generate the strongest signals depending on many factors.
Circular antennae seem to have the all around good result.
Coax is generally used to transfer the signal captured on the antenna to the radio input. The grounded shield will reduce noise interference.
Here's a link to a large thread with examples of DIY antennae used by Phorum members. One of the posts I explain my Ethernet Antenna where I used six feet of ethernet cable to make a 48 foot antenna coiled up in the radio cabinet.
