“My problem is I have 4 cats, they love to chew on wires smaller then network cable. So the wire antenna is very attracting to them.”
When pets such as cats or dogs start to chew on things like wiring or other objects, it usually means their teeth and/or gums are bothering them. I would suggest taking the kiddy kittys to a kitty dentist.
Another suggestion is to enclose the wire or relocate as suggested by other members. Using the solid copper wire is another good suggestion. However I would be concerned about them moving up in gauge and start chewing on power cords, where the zap from that will be more than the result of curiosity.
“At the low power levels these transmitters operate at, you probably would not damage them by connecting to a common antenna. However, they most likely will not provide the same range as each would load down the others output depending on the individual output coupling each uses. There are devices that will allow using a common antenna with two transmitters but would be cost prohibitive for this application.”
The suggestion to combine the AM and FM into a common antenna without a proper combiner is not recommended no matter the low power levels of the transmitters. Without proper combining and isolation, no telling what kind of inter-mix products will be produced or what kind of internal inter-mixing ailments will develop inside either transmitter. With the right know how a combiner could be constructed pretty easily and use of typical junk parts. Key is to provide isolation and coupling transfer effectiveness.
