[time-nuts] Rooftop GNSS antenna mounting recommendations

[Matt Huszagh]

Hi,

I'll be mounting a GNSS antenna to my roof for timing applications and
would appreciate recommendations for the best way to do this. The
portion of the roof where the antenna will be mounted is flat. I'd
prefer to avoid drilling or screwing into the roof if possible. But, if
there's a safe and reversible way to do this, I'm ok with that.

I found a method described by sparkfun that involves using an anchor in
a cinder block:

This seems like an easy and low-cost method. Given the weight of the
cinder block, I wouldn't expect the antenna to move. Thoughts? Any
potential problems with this? Other methods that work well?
