Personally, height matters to me. The higher the better, and yes, even
with 160-80 ... if you can achieve it?--1 ft. higher, go for it.

As close as you can, drive a good copper ground post, tie every ground
you can find to it ... mains ground?, your coax?--yes!, everything! ...
ground is good, and the closer the earth ground is to you--only the
better ...
