Hardy guy weighing-in!
Mark and Daniel are both correct, except:
Bullet point 6 should read:
Any change in transmit antenna polarization

Daniel’s points below come from § 1.929(d) Classificatio
This is from a presentation I wrote while I was at Bridgewave... this
dates back to 2011. Assuming the FCC has not changed their rules on any
of this... it should still be good. I believe Mr. Hardy reviewed this
for me back then :-)
Any change made to an existing license or PCN that introduces a
The FCC asks for both tower base MSL (mean sea level) and the AGL (above ground
level). So if you are on a 100’ tower at 100’ you report 100’ . You report
the ground elevation at whatever it actually is - including the 15’

I wonder if that Hardy guy has an opinion.

My biggest issue is what agl is based off of. We just did a link where they
built the ground up 15 feet, are we 115 feet or 100 feet if the structure
is 100 feet tall? How are propagation profiles accounting for discrepancies
like this? Is there and actual way to calculate amsl?

Ok I think I answered that myself. Part 101 calls for accuracy to +/- 1
meter. I thought someone told me there was more play than that.
