How can you test your signal strength/ Output

[midwestclubber]

So, I spend alot of time, just trying to squeaze out a bit more coverage, and my Original way, was to put the radio in the house on the adjacent frequency, and position the transmitter to where the signal gets the most bleed over to the adjacent frequency, but this doesnt seem to hold true for coverage, the transmitter position, in which comes in strongest on the inside stereo, doesnt seem to match up with the signal strength outside, and the overall coverage, so I thought using the cars stereo to check bleedover on adjacent signals would work, but it is really hard to keep running inside, moving the TX, and running a hundred feet out to car to check, its just not an efficient way to do this. If I had a field strength meter, I wouldnt have this problem. You would think just placing the TX as high up as you can get it, IN A WINDOW would be the best way to get covergage, but that doesnt seem to hold true either. Any body got any methods that work, or suggestions?

I expect you are writing about Part 15 AM systems. If so, tuning for max "bleedover" to an adjacent channel isn't the best approach, because Part 15 AM tx antennas are so narrow that you are probably peaking its performance on the AM sideband closest to your adjacent frequency -- and DE-tuning it for best response centered on the tx carrier and both of its sidebands.

Best antenna match and response across the whole AM channel is what you need for best on-channel performance.

Any nearby, linear conductors (such as house wiring, eavestroughs, aluminum siding etc) will affect the radiation pattern of an antenna.

Best FM omnidirectional coverage outside the house needs the tx antenna to be installed above roof level or maybe in the attic, and with its antenna vertical. But then coverage inside the house may not be as good.

I can get it up to nearly the ceiling, but wouldnt placing it in the window be better then placing it slightly above the window? Also, wouldnt the center of the window, be better than the top? The Transmitter has the transmitter built into the power cord, or inside the transmitter, its not a Metal Rod antenna, and I dont think I can use one of them. What it is, is a Sirius-Visor Unit, used mainly to re-broadcast one of the Sirius stations to friends in the neighborhood. www.sirius.com/servlet/ContentServer? It goes farther than my Ramsey 25b actually.
