Likely intended to replace their T-Band channels.

It could also be used to add to an existing trunked system such as SC21 or CC Sheriff.

I still hear them on UHF. Are you sure they are not APX7000 700/800 R2 UHF radios?

Based on the fact that their still using uhf I would say its a safe better to say their uhf. Might have been in over sight by looking at the antenna, apx antenna kinda mess with the principle of tring to cipher out what band its really on. They also might be part of the grant, but from them licensing their own frequencies I would say that they might opt out of starcom 21 for a few reasons at the local level. Makes sense long term, wish more departments understood this instead of getting on the band wagon.

Maybe it would be a good idea to "give them a listen" before posting?

Could be UHF R2 / 800 MHZ but definitely APX radios. Yes I still hear on UHF also.

The only appearance difference between the UHF/700/800 APX's and the VHF/700/800 ones are the length of the tri-band* antennas. The VHF ones are marginally longer and indecipherable as such without direct comparison.

I just noticed that the freqs are licensed as conventional (non-trunked) so perhaps they will put up a pair of conventional repeaters. They are licensed for both TDMA and FDMA (Phase 1 and 2). I have never heard of Phase 2 being used in a conventional mode but I suppose it is possible...

I still think they intend on adding these to a trunked system, either the Cook County node or the State node of StarCom21. While this would require a new license for a different service type, once they have the freqs licensed it is fairly easy to change.

* The three bands are 700/800, GPS and either VHF or UHF.

I believe its for their conventional P25 system. That was the only document I came across browsing the web.

I've had the two frequencies listed programmed into my PSR-500 since I got it last December and as of today have NOT heard a single peep. Not even a key-up or call sign...

I have them set up as a One Frequency Trunk with both frequencies in the site. As of ten minutes ago, no activity to report. Implementation in July 2018 it says, so keep an ear to it. 2 frequencies, 2 slots each is probably how this will be set up. Might be some low-power usage too, so program accordingly. Keep your fingers crossed for no encryption.
