    Arrow FM Transmitter Attenuator

    For those looking to decrease the range of your FM transmitter, these little jokers will be a BIG help.

    These attenuator's can knock the power down so the FCC doesn't come knocking on your door.

    How far are you allowed to broadcast?

    I think, not sure, but 200ft from the antenna.

    Mmmm... Was thinking of leaving my antenna up year round so I can hear my tunes at the neighborhood pool on a radio. Guess not.

    Was also thinking grand and having more than just my lights hooked up to a system - put several streets together with lights. That would be a FUN show!

    William, I saw this on LOR or PC too. I'm am concerned with this attenuator. His data is empirical and has flaws. He did not check the VSWR when he inserted the attenuator. I would be far more inclined to accept his data had he measured the VSWR. If the VSWR is too high it will blow up the Ramseys and the EDMs simply shuts off. I think he has an impedance mismatch.

    I didn't think about that Al.

    If his VSWR is too high, poof goes the transmitter.

    I'd like to see a real measurement too.
