I have never trusted tilt markings because I suspect there's only so
much manufacturing tolerance they can/will put put into little stamped
markings. Then sometimes there's a 1/10th inch or so of play in the
assembly of the hardware. A tenth inch might be half a degree, and
that's a lot.
I'm currently having a battle of wills with a tower climber about this
very topic. He has a digital level in his truck, but wants to trust the
tilt markings because it's easier and less to carry.

Manufacturer tilt marks do not correspond with plumb... I verified not
a problem with 3.65 alpha antennas... 2.3 and 2.5 big problem with the
65 deg t0

So why exactly is it 2* off?

I guess I'll treat this as a lesson learned...my point is, our mounts
are level... Why should I not trust what a manufacturer has made...
After all they know the importance of accuracy in the Rf world.

I hope you never go by the degree markings on an antenna!

Why would you not use the inclinometer to verify the antenna tilt?

Well, I hope Alpha will be compensating us for every site we need
to revisit. I AM absolutely Furious!!
Every single one of our sites we use a level or inclometer on a
mount for 0 deg or compensate... Set the antenna for 3-4 degrees...
according to our RNP and call it a day.
We have discovered that ALL our ALPHA degree markings are 2 degrees
off!
This means my entire network... Which has felt like self
interference... Is self interference. All the antennas are 1 to 2
degrees tilt!!!
Please see attached photos...
We used a sunsight azimuth and tilt meter to confirm. We used the
sunsight on a new site build and discovered the anomaly.
Telrad needs to issue a bulletin and check the T0 3.65 too.
Off we go to rescue our network....
