I asked Keith about doing the same thing, and he said it wouldn’t work because the AM1000 expects a high impedance antenna, and the Isotron has a low 50ohm impedance. The reason I asked is that we have RG8 running through our building and up a tower that would have worked perfectly betwen those two devices if it wasn’t for the impedance mis-match.
Don’t know if he really thinks it is a bad idea, or if it’s nonsense. He also said that the part 15 rules might expect that the transmitter gets used with the antenna that hey used to certify the transmitter. Again, I don’t know if that is right or wrong since I didn’t check into it. And I can’t seem to get anyone here interested in an AM device that will at least reach off campus.
