32 radials is quite a bit of wire, especially in elevated installations (i.e. roofs). Getting less concerned with the cost of radials and more concerned with managing the wire mess, wind blown potential and long term maintenance.
Big question for Part 15’ers is with their existing radial installations, what are they using for radial collar (ring around radiator to which the radial wires are attached)? I’ve seen a pretty common square aluminum solution widely used elsewhere, but it’s pricey (i.e. $50-$100) and seems targeted at ground level installs that are also cemented in place.
