Hopefully the new 71MHz allocation will soon attract other amateurs interested in DATV. My own equipment was easily adapted from earlier tests on 6m; it's not tidy yet but it is functional and clean spectrum wise.
So just a short post to say I ordered a Sirio 3 element beam and I'm very impressed with the build quality. It won't be erected at the home QTH as I'm trying to keep a low profile. It will however be used /P on the hills.
Antennas are sexy but try convincing your neighbours.
