symmetric about the boresight axis - i.e. provided your "azimuth" and "elevation" are defined with respect to the antenna orientation, just discard the azimuth parameter and look up the elevation into a … ). Anyway in real life the gain pattern is influenced to at least that extent by the surrounding geometry of whatever it's mounted to; those effects can be simulated but would require more data on the antenna construction to do so. …

Yes. With a suitable matching network (which may be tricky since matching networks are typically themselves somewhat narrowband) you can use that antenna and a frequency-agile transceiver such as the … CC1101/CC1110 at any of the frequency ranges quoted. An alternative is to use a broadband antenna such as the log-periodic which you could construct yourself or print onto the PCB. That would cover …

Yes, a passive repeater such as you describe can work, however it does incur losses due to the cable, connectors and antenna efficiencies. Whether these losses exceed the attenuation you would get with no repeater but a wall in the way is situation dependent. …
