Thanks, what about for a analog scanner?
The most common models of the Remtronix antennas are tailored toward 700/800MHz systems. They work OK for Uhf, but are not a good choice for Vhf-high frequencies. It's the frequency that matters for an antenna, not whether the system you are trying to hear is digital or analog.
As noted in your other thread,
WS1040: - Help, your main problem is both simulcast, as well as talkgroups using P25 Phase II talkgroups, which your scanner cannot receive. A change of antenna is not going to be helpful, no matter which one you select.
