Were I live is in the low part of a valley so my signal seems to get trapped here. I do own land with the highest hill in our community and I was thinking of taking on the project of moving my sstran tx and home brewed antenna to the top of this hill
the only problem is its 400ft to the top from my studio. Right now I run my audio to my tx with rg-6 75 ohm shielded cable and was thinking I would do the same. Im just looking for every ones input. Can this be done and whats the best setup and what size wize should I run for the power?
thank for all your help,
Brian
Powering the transmitter might be the biggest issue. As far as audio goes, I would probably convert the audio to +4db balanced line level, and put a balanced to unbalanced transformer (600 to 10K ohm) on the end connected to the transmitter. In that configuration, I wouldn't be worried about audio signal loss, I used to run microphone level signal farther than that every day. But I wouldn't try to send an unbalanced signal that far unless I had no other choice. Sescom has good prices on transformers. If you boost the level up to +4db, then you will probably have to pad it back down before connected to the transmitter. You can find calculators for H and T pads through a search engine, after that just solder up the resistors and you're done.
You can also run DC(pure DC!not AC)up the same wire you use for audio. Simply add isolation capacitors at each end. Use good quality Mylar caps 3 to 10 uf at 200 or more volts. I would also add some sort of lightning protection so it doesnt find its way to your studio. Fuses,loops at each end of the wire,MOV's across the line and to ground would be a good start. Regards,Lee

Have you tried that product? Might be useful to have a pair of those around if they really do work well. It's hard to build the same thing out of transformers for the same price, and then you would still have the labor on top of that.
That looks like a good way of linking other transmitters if you could get permision to run wire on other peoples land.
How about power could I run a dual RG-6 one for my AC power for my sstran and one for my audio?
How much drop in voltage do you think I might have? I am running my power on the sstran provided wall plug that has an output of 18Vac 500mA.
We use one at work but not for the station. It works really well.
Ours is on a 100' run over ethernet and it works great.
