Yes, it can make a big difference. Lightning arresters are NOT just protecting
you from a strike on your antenna. They also protect you from a strike on the
power line or even just to the ground nearby that causes the ground system
voltage to rise while the voltage on the center of the coax doesn't... if the
arrester is not very close to the radio it delays the arrester action which can
make your radio the easiest path from ground to the center conductor... in hv
engineering terms its called a backflashover, which is caused when lightning
hits the ground system causing a flashover to a power conductor.

Subject: [TowerTalk] Arrestor placement
Hello all,Somehow I have gotten the idea that one's lightning arrestors are
best placed at the bottom of the tower. This seems logical to me. Then I came
across another piece that said, no, arrestors are to be placed at the shack
entrance panel. Which is it? Or does it matter? 73, David, AA9G
