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.
