IP Radio STL

One concern I have is locating both the radio and dish together. It seems that a better configuration would be to place the radio at ground level where it can be serviced rather than on a tower. The intergrated solutions that I've seen certainly wouldn't allow this.

Thanks again for all your suggestions and help.

Other than firmware updates there isn't anything to service.and those are done over the lan.you can get units that have an external antenna connection like some of the tranzeo units .I copied my config and loaded it in a stand by pair just in case of failure.I know engs that have years of service on these units with no failures.but i just like some redundacy in case.
 
coax loss at 5 ghz is rather high. In my opinion, not cost effective to locate radios at ground and maintain any kind of meaningful sensitivity.

I did have a link with some tranzeo 900mhz radios on 7/8 heliax for a while, worked alright...but even the loss at 900mhz is bad when you only have 400mw of power and a noise floor of -75 dbm

had to get the signal up to -35dbm for it to work reliably carrying realtime audio, then one end took a lightning hit and it was over.
 
Radio closest to antenna - period
That's why are both in one 'box' in todays units. Using Mikrotik board, for example, you need at least 1m cable + 2 connector and "pig-tail" (3rd connector), so many places to lose dB's.

Like with all STL's, you need a backup. On 950mhz, the backup is in the rack. At 5.8ghz, the backup is on the tower.
 
Speaking/thinking of STL backup; I'm wondering what to do with a 'same city' studio~transmitter situation wherein the transmitter has a phone line for control.

In a crisis, would you connect the lines and couple mono-audio via the phone line pair or would you take a laptop/desktop computer to the transmitter and use the dial-up modem to grab audio from the studio's feeder-stream?

On this AM that I'm considering the IP radio STL, I kept the station up by using the POTS for the Burk remote control. I took a Tieline to the xmtr and connected it to the input of the Orban. I then dialed in over the POTS line. Kept the station on for days until the telco restored the program loop.

At another station, the primary program audio comes in on a T1 and has for back-up both a Pulsecom program loop and aural STL. The fun comes when the T1 goes down because the T1 is used to remotely switch among sources. It really needs a silence detector, but since management hasn't approved that just yet, someone has to drive to the xmtr to switch sources.
