As ya’ll probably know by now I have an elevated installed Procaster on the third floor attic window of my house. The only wire running to it is the supplied 4 conductor cable that runs from the transmitter, across the attic and into the studio. This cable has two audio leads, and power. It plugs into the supplied studio module (or whatever they call it) into which the audio plugs in from source, and the wall wart power supply plugs in. It also houses the audio processing, etc so if you want to make changes to levels, compression, eq, etc you don’t have to get out to to where your transmitter is. And that’s it.
Had I done my installatiion as shown in the supplied manual for the certified FCC transmitter, there would also be a long ground lead from the lug on the transmitter, down the side of ths house to a ground rod or cold water pipe. It’s right there on the front page of the manual showing a “typical installation”. In fact, the install as shown, except for the ground lead, looks nearly exactly like mine. Having read the rules on the internet, and doing a lot of research before purchasing my transmitter, I already figured the long ground lead would be an issue. So I never put one on.
Some will say that there must be some sort of ground between the transmitter and studio through that cable. Not that I can find. I show no continuity to ground anywhere. Nonetheless, if I had this same transmitter ground mounted, it would STILL require the same cable, as supplied, to bring it power and audio. So any effect that cable might have would still exist in a ground mounted installation.
During the day I get a solid 7100 feet (measured in a straight line) from the transmitter. I drive home from work past this spot every day around noon, and it’s always there. At night, maybe two blocks. Some nights quite a bit more.
Them’s the facts from Bovey. How or why, I’m not to concerned with.
