We are working on this now. Studio is 10 miles away from first site.
They have a 950 analog STL. Not very good LOS, so a direct shot using
5GHz won't work, licensed out of the question. Their other station has
two STLs using a building in the middle. The first site will be getting
an AM/FM translator and they do not want to spend the money on another
STL. So we are building PTPs to them for the translator and also backup
for their analog links. They ride our 11GHz most of the way so they are
happy about that. They were also concerned about outages and latency
over the interwebs. I can understand that. Their studio Comcast service
sucks.
These are the kind of customers you want (tower owners). We're doing it
for free. Give them free internet at the sites, they let us put up
whatever we want, within reason.

What do they do when the STL fails? Do they have a way to get some
generic stuff playing while it's fixed?

The public internet yes, but if you have pretty good control over
the route then it should not be a problem. Many times the traffic
is like a two hop distance. If your upstream provider peers with
the station provider I can’t see a big problem. Or better yet,
your upstream provider serves the station studio or whatever the
other end is...

I won’t claim to be an expert by any means on STL links. I’ve
engineered backhaul links for broadcast guys though so I know a
bit about the requirements.
IMHO it’s a bad idea to put STL traffic on the internet. Packet
loss, jitter, latency are all very important metrics. Capacity is
low… maybe 2Mbps tops for HD audio (I guess it could be more
depending on how many stations are transmitting from that
antenna). Give them a dedicated link.
Telos/Axia and Whetstone are the two encoder manufacturers I’ve
run across.
Jeff Holdenrid at DoubleRadius would be a great contact if you’re
looking for ways to make the STL work.
Thank you,

If someone has any info on the STL links. Send me a message off list.
I wanna know everything possible about it

Also keep in mind you're supposed to lower the power when

We're on a very similar site. We're running 100Mb

Stay away from the driven elements as
far as you can.
Some use ferrite cores on the cable
too. Can’t hurt.
